Thanks. + + +Intro +===== + +Yes, you can program u-boot onto the flash of your Palm Treo 680 so that u-boot +(then Linux, Android, ...) runs at power-up. This document describes how, and +gives some implementation details on this port of u-boot and describes how the +Treo 680 boots from reset. + +But first, I probably don't need to tell you that after doing this, your phone +will no longer run PalmOS. You *may* be able to later restore your phone to its +original state by creating a backup image of the flash before writing u-boot +(details below), but this is not heavily tested and should not be relied upon. +There is also the possibility that something may go wrong during the process of +programming u-boot, leaving you with a bricked phone. If you follow these +instructions carefully this chance will be minimized, but I do not recommend +that you program u-boot onto a phone that you can not afford to lose, and +certainly not one that contains important data that is not backed up elsewhere. +I AM NOT RESPONSIBLE FOR THE LOSS OF YOUR PHONE. DO THIS AT YOUR OWN RISK. +Having said that, feel free to send me a note cursing me out if something does +go wrong, but please tell me what happened exactly. For that matter, I'd love +to hear from you if you succeed. + + + +Details on the SPL +================== + +The docg4 features a 2k region at the start of its address space that interfaces +to the system bus like a NOR flash. This allows the docg4 to function as a boot +ROM. The Treo 680 uses this feature. The contents of this 2k region are +write-protected and can not be reprogrammed. Fortunately, the code it contains +does what we need to do, at least partially. After some essential hardware +initialization (like the SDRAM controller), it runs an IPL (initial program +loader) that copies 128K (no more, no less) from flash to a fixed address in +SDRAM (0xa1700000) and jumps to it. 128K is too small for u-boot, so we use it +to load a u-boot secondary program loader (SPL). But since our SPL only +occupies a little over 1k, we can economize on flash usage by having the IPL +load a portion of u-boot proper as well. We let the IPL load the first 128k of +a concatenated spl + u-boot image, and because the SPL is placed before u-boot +proper, the IPL jumps to the SPL, which copies the portion of u-boot that the +IPL has already loaded to its correct SDRAM address, and then loads the +remainder of u-boot and jumps to it. + + + +The docg4's "reliable mode" +=========================== + +This is a special mode of operation of the docg4's integrated controller whereby +consecutive pairs of 2k regions are used in parallel (in some fashion) to store +2k of data. In other words, the normal capacity is halved, but the data +integrity is improved. In this mode, the data is read or written from pages in +even-numbered 2k regions (regions starting at 0x000, 0x1000, 0x2000, ...). The +odd-numbered 2k regions (regions starting at 0x800, 0x1800, 0x2800, ...) are +transparently used in parallel. In reliable mode, the odd-numbered 2k regions +are not meant to be read or written directly. + +Reliable mode is used by the IPL because there is not enough space in its 2k +footprint to implement the BCH ecc algorithm. Data that is read while reliable +mode is enabled must have been written in reliable mode, or the read fails. +However, data written in reliable mode can also be read in normal mode (just not +as reliably), but only from the even-numbered 2k regions; the odd-numbered 2k +regions appear to contain junk, and will generate ecc errors. When the IPL and +SPL read from flash, the odd-numbered 2k regions are explicitly skipped. The +same is true for the flash_u-boot utility when it writes the u-boot image in +reliable mode. + +The docg4 Linux driver supports writing in reliable mode (it is enabled by the +module parameter), but not reading. However, the u-boot docg4_spl driver does +read in reliable mode, in the same fashion as the IPL. + + + +Details on the IPL and its data format +====================================== + +Starting from block 5 and counting upward, the IPL will search for and load the +first two blocks it finds that contain a magic number in the oob of the first +page of the block. The contents are loaded to SDRAM starting at address +0xa1700000. After two blocks have been loaded, it jumps to 0xa1700000. The +number of blocks loaded and the load address in SDRAM are hard-coded; only the +flash offset of the blocks can vary at run-time (based on the presence of the +magic number). + +In addition to using the docg4's reliable mode, the IPL expects each 512 byte +page to be written redundantly in the subsequent page. The hardware is capable +of detecting bit errors (but not correcting them), and if a bit error is +detected when a page is read, the page contents are discarded and the subsequent +page is read. + +Reliable mode reduces the capacity of a block by half, and the redundant pages +reduce it by half again. As a result, the normal 256k capacity of a block is +reduced to 64k for the purposes of the IPL/SPL. + +For the sake of simplicity and uniformity, the u-boot SPL mimics the operation +of the IPL, and expects the image to be stored in the same format. + + + +Instructions on Programming u-boot to flash +=========================================== + +To program u-boot to your flash, you will need to boot the Linux kernel on your +phone using a PalmOS bootloader such as cocoboot. The details of building and +running Linux on your Treo (cross-compiling, creating a root filesystem, +configuring the kernel, etc) are beyond the scope of this document. The +remainder of this document describes in detail how to program u-boot to the +flash using Linux running on the Treo. + + + +Hardware Prerequisites +====================== + +A Palm Treo 680: + (dugh) + +A Palm usb cable: + You'll need this to establish a usbtty console connection to u-boot from a + desktop PC. Currently there is no support in u-boot for the pxa27x keypad + (coming soon), so a serial link must be used for the console. + These cables are still widely available if you don't already have one. + +A Linux desktop PC. + You may be able to use Windows for the u-boot console if you have a usb driver + that is compatible with the Linux usbserial driver, but for programming u-boot + to flash, you'll really want to use a Linux PC. + + + +Treo-side Software Prerequisites +================================ + +Linux bootloader for PalmOS: + + Cocoboot is the only one I'm aware of. If you don't already have this, you + can download it from + https://download.enlightenment.org/misc/Illume/Treo-650/2008-11-13/sdcard-base.tar.gz + which is a compressed tar archive of the contents of an sd card containing + cocoboot. Use mkdosfs to create a fat16 filesystem on the first primary + partition of the card, mount the partition, and extract the tar file to it. + You will probably need to edit the cocoboot.conf file to customize the + parameters passed to the kernel. + + + +Linux kernel: + + The kernel on the Treo 680 is still a little rough around the edges, and the + official kernel frequently breaks on the Treo :( A development kernel + specifically for the Treo 680 can be found on github: + http://github.com/mike-dunn/linux-treo680 + The master branch of this tree has been tested on the Treo, and I recommend + using this kernel for programming u-boot. As of this writing, there may be a + bug in the docg4 nand flash driver that sometimes causes block erasures to + fail. This has been fixed in the above tree. + + If you choose to use the official kernel, it must contain the docg4 driver that + includes the reliable_mode module parameter. This was a later enhancement to + the driver, and was merged to the kernel as of v3.8. Do not try to use an + earlier kernel that contains the docg4 driver without support for writing in + reliable mode. If you try to program u-boot to flash with the docg4 driver + loaded without the reliable_mode parameter enabled, you *will* brick your + phone! + + For the purpose of programming u-boot to flash, the following options must be + enabled in the Treo kernel's .config: + + CONFIG_MTD=y + CONFIG_MTD_CMDLINE_PARTS=y + CONFIG_MTD_CHAR=y + CONFIG_MTD_NAND_DOCG4=m + + Note that the docg4 nand driver is configured as a module, because we will + want to load and unload it with reliable_mode enabled or disabled as needed. + + You will also need to specify mtd partitions on the kernel command line. In + the instructions that follow, we will assume that the flash blocks to which + u-boot will be programmed are defined by the second partition on the device. + The u-boot config file (include/configs/palmtreo680.h) places the u-boot image + at the start of block 6 (offset 0x180000), which is the first writable + (non-protected) block on the flash (this is also where the PalmOS SPL starts). + The u-boot image occupies four blocks, so to create the u-boot partition, pass + this command line to the kernel: + mtdparts=Msys_Diskonchip_G4:1536k(protected_part)ro,1024k(bootloader_part),-(filesys_part) + This will create three partitions: + protected_part: the first six blocks, which are read-only + bootloader_part: the next four blocks, for the u-boot image + filesys_part: the remainder of the device + The mtdchar kernel device driver will use device nodes /dev/mtd0, /dev/mtd1, + and /dev/mtd2 for these partitions, respectively. Ensure that your root file + system at least has /dev/mtd1 if you are not running udev or mdev. + + +Userspace Utilities: + + In addition to everything necessary to provide a useful userspace environment + (busybox is indispensable, of course), you will need the mtd-utils package on + your root filesystem. I use version 1.5.0 of mtd-utils, and I suggest you use + this version as well, or at leat a version very close to this one, as + mtd-utils has tended to be fluid. + + Note that busybox includes a version of mtd-utils. These are deficient and + should not be used. When you run one of these utilities (nanddump, etc), + ensure you are invoking the separate executable from mtd-utils, and not the + one built into busybox. I recommend that you configure busybox with its + mtd-utils disabled to avoid any possibility of confusion. + + You will also need to cross-compile the userspace Linux utility in + tools/palmtreo680/flash_u-boot.c, which we will run on the Treo to perform the + actual write of the u-boot image to flash. This utility links against libmtd + from the mtd-utils package. + + + +Desktop PC-side Software Prerequisites +====================================== + +Terminal emulator application: + minicom, kermit, etc. + + +Linux kernel: + Compiled with CONFIG_USB_SERIAL enabled. Build this as a module. + + + +Recommended (Not directly related to u-boot) +============================================ + +Working directly on the Treo's tiny screen and keypad is difficult and +error-prone. I recommend that you log into the Linux kernel running on your +Treo from your desktop PC using ethernet over usb. The desktop's kernel must be +configured with CONFIG_USB_USBNET, CONFIG_USB_NET_CDCETHER, and +CONFIG_USB_NET_CDC_SUBSET. The Treo's kernel will need CONFIG_USB_ETH, and its +init script will need to start an ssh daemon like dropbear. Note that the usb0 +network interface will not appear on the desktop PC until the Treo kernel's usb +ethernet gadget driver has initialized. You must wait for this to occur (watch +the PC's kernel log) before you can assign usb0 an ip address and log in to the +Treo. If you also build the Treo's kernel with CONFIG_IP_PNP enabled, you can +pass its ip address on the kernel command line, and obviate the need to +initialize the network interface in your init script. + +Having the Palm usb cable connected to the host has the added benefit of keeping +power supplied to your Treo, reducing the drain on the battery. If something +goes wrong while you're programming u-boot to the flash, you will have lots of +time to correct it before the battery dies. + +I have encountered a situation where the kernel is sometimes unable to mount a +root filesystem on the mmc card due to the mmc controller not initializing in +time, (and CONFIG_MMC_UNSAFE_RESUME doesn't seem to help) so I recommend that +you build a minimal root filesystem into the kernel using the kernel's initramfs +feature (CONFIG_BLK_DEV_INITRD). If you want your root filesystem on the mmc +card, your init script can mount and switch_root to the mmc card after a short +sleep. But keep in mind that in this case you won't be able to use an mmc card +to transfer files between your desktop and the Treo once Linux is running. +Another option for transfering files is to mount an nfs filesystem exported by +the desktop PC. For greatest convenience, you can export the root filesystem +itself from your desktop PC and switch_root to it in your init script. This +will work if your initramfs init script contains a loop that waits for you to +initialize the usb0 network interface on the desktop PC; e.g., loop while a ping +to the desktop PC returns an error. After the loop exits, do the nfs mount and +call switch_root. (You can not use the kernel nfsroot feature because the +network will not be up when the kernel expects it to be; i.e., not until you +configure the usb0 interface on the desktop.) Use the nfs 'nolock' option when +mounting to avoid the need to run a portmapper like rpcbind. + + + +Preliminaries +============= + +Once Linux is running on your Treo, you may want to perform a few sanity checks +before programming u-boot. These checks will verify my assumptions regarding +all the Treo 680s out there, and also ensure that the flash and mtd-utils are +working correctly. If you are impatient and reckless, you may skip this +section, but see disclaimer at the top of this file! + +Load the docg4 driver: + + $ modprobe docg4 ignore_badblocks=1 reliable_mode=1 + +We tell the driver to use the docg4's "reliable mode" when writing because this +is the format required by the IPL, which runs from power-up and loads the first +portion of u-boot. We must ignore bad blocks because linux mtd uses out-of-band +(oob) bytes to mark bad blocks, which will cause the blocks written by PalmOS to +be misidentified as "bad" by libmtd. + +Check the kernel log to ensure that all's well: + + $ dmesg | tail + <... snip ...> + docg4 docg4: NAND device: 128MiB Diskonchip G4 detected + 3 cmdlinepart partitions found on MTD device Msys_Diskonchip_G4 + Creating 3 MTD partitions on "Msys_Diskonchip_G4": + 0x000000000000-0x000000180000 : "protected_part" + 0x000000180000-0x000000280000 : "bootloader_part" + 0x000000280000-0x000008000000 : "filesys_part" + +Ensure that the partition boundaries are as shown.

There is a slight chance that one or +more of the four blocks that we will use for u-boot is listed in the table, so +use nanddump to inspect the table to see if this is the case: + + $ nanddump -p -l 512 -s 0x2000 -o /dev/mtd0 + ECC failed: 0 + ECC corrected: 0 + Number of bad blocks: 0 + Number of bbt blocks: 0 + Block size 262144, page size 512, OOB size 16 + Dumping data starting at 0x00002000 and ending at 0x00002200... + 0x00002000: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff + <... snip ...> + +The format of the table is simple: one bit per block, with block numbers +increasing from left to right, starting with block 0 as the most significant bit +of the first byte. A bit will be clear if the corresponding block is bad. We +want to use blocks 6 throgh 9, so both of the two least significant bits of the +first byte must be set, as must the two most significant bits of the second +byte. If this is not true in your case (you are very unlucky), you should use +the first contiguous set of four good blocks after block 6, and adjust the +partition boundaries accordingly. You will also have to change the value of +CONFIG_SYS_NAND_U_BOOT_OFFS in include/configs/palmtreo680.h and recompile +u-boot. Because the two blocks loaded by the IPL do not have to be contiguous, +but our SPL expects them to be, you will need to erase any good blocks that are +at an offset prior to CONFIG_SYS_NAND_U_BOOT_OFFS, so that the IPL does not find +the magic number in oob and load it. Once you have done all this, the +instructions in this file still apply, except that the instructions below for +restoring the original PalmOS block contents may need to be modified. + +Next, use nanddump to verify that the PalmOS SPL is where we expect it to be. +The SPL can be identified by a magic number in the oob bytes of the first page +of each of the two blocks containing the SPL image. Pages are 512 bytes in +size, so to dump the first page, plus the oob: + + $ nanddump -p -l 512 -s 0 -o /dev/mtd1 + ECC failed: 0 + ECC corrected: 0 + Number of bad blocks: 0 + Number of bbt blocks: 0 + Block size 262144, page size 512, OOB size 16 + Dumping data starting at 0x00000000 and ending at 0x00000200... + 0x00000000: 0a 00 00 ea 00 00 00 00 00 00 00 00 00 00 00 00 + <... snip ...> + 0x000001f0: 13 4c 21 60 13 4d 2a 69 13 4b 29 69 89 1a 99 42 + OOB Data: 42 49 50 4f 30 30 30 10 3a e2 00 92 be a0 11 ff + +Verify that the first seven bytes of oob data match those in the above line. +(This is ASCII "BIPO000".) + +Do the same for the next block: + $ nanddump -p -l 512 -s 0x40000 -o /dev/mtd1 + +The first seven oob bytes in last line should read: + + OOB Data: 42 49 50 4f 30 30 31 81 db 8e 8f 46 07 9b 59 ff + +(This is ASCII "BIPO001".) + +For additional assurance, verify that the next block does *not* contain SPL +data. + + $ nanddump -p -l 512 -s 0x80000 -o /dev/mtd1 + +It doesn't matter what the oob contains, as long as the first four bytes are +*not* ASCII "BIPO". PalmOS should only be using two blocks for the SPL +(although we will need four for u-boot). + +If you want, you can back up the contents of bootloader_part to a file. You may +be able to restore it later, if desired (see "Restoring PalmOS" below). + + $ nanddump -l 0x100000 -s 0 -o -f bootloader_part.orig /dev/mtd1 + +nanddump will spew voluminous warnings about uncorrectable ecc errors. This is +a consequence of reading pages that were written in reliable mode, and is +expected (these should all occur on pages in odd-numbered 2k regions; i.e., +0x800, 0xa00, 0xc00, 0xe00, 0x1800, 0x1a00, ...). The size of the file +bootloader_part.orig should be 1081344, which is 2048 pages, each of size 512 +plus 16 oob bytes. If you are using initramfs for the root filesystem, don't +forget to copy the file to permanent storage, such as an mmc card. + +If all of the above went well, you can now program u-boot. + + + +Programming u-boot +================== + +Our u-boot includes a small SPL that must be prepended to u-boot proper. From +the base u-boot source directory on your desktop PC: + + $ cat spl/u-boot-spl.bin u-boot.bin > u-boot-concat.bin + +cd to the tools/palmtreo680/ directory, and cross-compile flash_u-boot.c for the +Treo: + + $(CC) -o flash_u-boot $(CFLAGS) $(INCLUDEPATH) $(LIBPATH) flash_u-boot.c -lmtd + +Substitute variable values from your cross-compilation environment as +appropriate. Note that it links to libmtd from mtd-utils, and this must be +included in $(LIBPATH) and $(INCLUDEPATH). + +Transfer u-boot-concat.bin and the compiled flash_u-boot utility to the Treo's +root filesystem. On the Treo, cd to the directory where these files were +placed. + +Load the docg4 driver if you have not already done so. + + $ modprobe docg4 ignore_badblocks=1 reliable_mode=1 + +Erase the blocks to which we will write u-boot: + + $ flash_erase /dev/mtd1 0x00 4 + +If no errors are reported, write u-boot to the flash: + + $ ./flash_u-boot u-boot-concat.bin /dev/mtd1 + +You can use nanddump (see above) to verify that the data was written. This +time, "BIPO" should be seen in the first four oob bytes of the first page of all +four blocks in /dev/mtd1; i.e., at offsets 0x00000, 0x40000, 0x80000, 0xc0000. + +Shutdown linux, remove and re-insert the battery, hold your breath... + + + +Enjoying u-boot +=============== + +After you insert the battery, the u-boot splash screen should appear on the lcd +after a few seconds. With the usb cable connecting the Treo to your PC, in the +kernel log of your PC you should see + + <6>usb 3-1: New USB device found, idVendor=0525, idProduct=a4a6 + <6>usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 + <6>usb 3-1: Product: U-Boot 2013.01-00167-gd62ef56-dirty + <6>usb 3-1: Manufacturer: Das U-Boot + +Load the usbserial module on your desktop PC: + + $ modprobe usbserial vendor=0x0525 product=0xa4a6 + +and run your favorite terminal emulation utility (minicom, kermit, etc) with the +serial device set to /dev/ttyUSB0 (assuming this is your only usb serial +device). You should be at the u-boot console (type 'help'). + +There is not much that is unique about using u-boot on the palm treo 680. +Kernels can be loaded from mmc, flash, and from the desktop PC via kermit. You +can expand the size of the second partition on the flash to contain a kernel, or +else put the kernel(s) in their own partition. + +Nand commands work as expected, with the excepton that blocks not written by the +linux mtd subsystem may be misidentified by the u-boot docg4 driver as "bad" if +they contain data in the oob bytes. This will be the case for the blocks +containing the u-boot image, for example. To work around this, use 'nand scrub' +instead of 'nand erase' to erase these blocks, and 'nand read.raw' to read them +to memory. (It would be useful if u-boot's nand commands provided a way to +explicitly ignore "bad" blocks, because read.raw does not perform ecc.) The +'nand dump' command will read these "bad" blocks, however. + +Currently u-boot itself can only be programmed to flash from Linux; there is no +support for reliable mode in u-boot's docg4 flash driver. This should be +corrected soon. + + + +Customizing +=========== + +If you change u-boot's configuration significantly (adding or removing +features), you may have to adjust the value of CONFIG_SYS_NAND_U_BOOT_SIZE. +This is the size of the concatenated spl + u-boot image, and tells the SPL how +many flash blocks it needs to load. It will be rounded up to the next 64k +boundary (the spl flash block capacity), so it does not have to be exact, but +you must ensure that it is not less than the actual image size. If it is larger +than the image, blocks may be needlessly loaded, but if too small, u-boot may +only be partially loaded, resulting in a boot failure (bricked phone), so better +to be too large. The flash_u-boot utility will work with any size image and +write the required number of blocks, provided that the partition is large +enough. + +As the first writable block on the device, block 6 seems to make the most sense +as the flash offset for writing u-boot (and this is where PalmOS places its +SPL). But you can place it elsewhere if you like. If you do, you need to +adjust CONFIG_SYS_NAND_U_BOOT_OFFS accordingly, and you must ensure that blocks +preceeding the ones containing u-boot do *not* have the magic number in oob (the +IPL looks for this). In other words, make sure that any blocks that previously +contained the u-boot image or PalmOS SPL are erased (and optionally written with +something else) so that the IPL does not load it. Also make sure that the new +u-boot starting offset is at the start of a flash partition (check the kernel +log after loading the docg4 driver), and pass the corresponding mtd device file +to the flash_u-boot utility. + +The u-boot built-in default environment is used because a writable environment +in flash did not seem worth the cost of a 256k flash block. But adding this +should be straightforward. + + + +Restoring PalmOS +================ + +If you backed up the contents of bootloader_part flash partition earlier, you +should be able to restore it with the shell script shown below. The first two +blocks of data contain the PalmOS SPL and were written in reliable mode, whereas +the next two blocks were written in normal mode, so the script has to load and +unload the docg4 driver. Make sure that the mtd-utils nandwrite and flash_erase +are in your path (and are not those from busybox). Also double-check that the +backup image file bootloader_part.orig is exactly 1081344 bytes in length. If +not, it was not backed up correctly. Run the script as: + + ./restore_bootpart bootloader_part.orig /dev/mtd1 + +The script will take a minute or so to run. When it finishes, you may want to +verify with nanddump that the data looks correct before you cycle power, because +if the backup or restore failed, your phone will be bricked. Note that as a +consequence of reliable mode, the odd-numbered 2k regions in the first two +blocks will not exactly match the contents of the backup file, (so unfortunately +we can't simply dump the flash contents to a file and do a binary diff with the +original back-up image to verify that it was restored correctly). Also, +nanddump will report uncorrectable ecc errors when it reads those regions. + +#!/bin/sh + +if [ $# -ne 2 ]; then + echo "usage: $0: <image file> <mtd device node>" + exit 1 +fi + +# reliable mode used for the first two blocks +modprobe -r docg4 +modprobe docg4 ignore_badblocks=1 reliable_mode=1 || exit 1 + +# erase all four blocks +flash_erase $2 0 4 + +# Program the first two blocks in reliable mode. +# 2k (4 pages) is written at a time, skipping alternate 2k regions +# Note that "2k" is 2112 bytes, including 64 oob bytes +file_ofs=0 +flash_ofs=0 +page=0 +while [ $page -ne 1024 ]; do + dd if=$1 bs=2112 skip=$file_ofs count=1 | nandwrite -o -n -s $flash_ofs $2 - || exit 1 + file_ofs=$((file_ofs+2)) + flash_ofs=$((flash_ofs+0x1000)) + page=$((page+8)) +done; + +# normal mode used for the next two blocks +modprobe -r docg4 +modprobe docg4 ignore_badblocks=1 || exit 1 +dd if=$1 bs=1 skip=$file_ofs count=540672 | nandwrite -o -n -s 0x80000 $2 - || exit 1 +modprobe -r docg4 + + +TODO +==== + + - Keypad support. + - Interactive boot menu using keypad and lcd. + - Add reliable mode support to the u-boot docg4 driver. + - U-boot command that will write a new image to the bootloader partition in + flash. + - Linux FTD support. + diff --git a/board/palmtreo680/palmtreo680.c b/board/palmtreo680/palmtreo680.c new file mode 100644 index 000000000..f4f6e1f5b --- /dev/null +++ b/board/palmtreo680/palmtreo680.c @@ -0,0 +1,148 @@ +/* + * Palm Treo 680 Support + * + * Copyright (C) 2013 Mike Dunn <mikedunn@newsguy.com> + * + * This file is released under the terms of GPL v2 and any later version. + * See the file COPYING in the root directory of the source tree for details. + * + */ + +#include <common.h> +#include <command.h> +#include <serial.h> +#include <nand.h> +#include <malloc.h> +#include <asm/arch/pxa-regs.h> +#include <asm/arch-pxa/pxa.h> +#include <asm/arch-pxa/regs-mmc.h> +#include <asm/io.h> +#include <asm/global_data.h> +#include <u-boot/crc.h> +#include <linux/mtd/docg4.h> + +DECLARE_GLOBAL_DATA_PTR; + +static struct nand_chip docg4_nand_chip; + +int board_init(void) +{ + /* We have RAM, disable cache */ + dcache_disable(); + icache_disable(); + + gd->bd->bi_arch_number = CONFIG_MACH_TYPE; + gd->bd->bi_boot_params = CONFIG_SYS_DRAM_BASE + 0x100; + + return 0; +} + +int dram_init(void) +{ + /* IPL initializes SDRAM (we're already running from it) */ + gd->ram_size = PHYS_SDRAM_1_SIZE; + return 0; +} + +#ifdef CONFIG_LCD +void lcd_enable(void) +{ + /* + * Undo the L_BIAS / gpio77 pin configuration performed by the pxa lcd + * driver code.
