* Patches by Denis Peter, 9 Sep 2003:U-Boot-0_4_8

  add FAT support for IDE, SCSI and USB

* Patches by Gleb Natapov, 2 Sep 2003:
  - cleanup of POST code for unsupported architectures
  - MPC824x locks way0 of data cache for use as initial RAM;
    this patch unlocks it after relocation to RAM and invalidates
    the locked entries.

* Patch by Gleb Natapov, 30 Aug 2003:
  new I2C driver for mpc107 bridge. Now works from flash.

* Patch by Dave Ellis, 11 Aug 2003:
  - JFFS2: fix typo in common/cmd_jffs2.c
  - JFFS2: fix CFG_JFFS2_SORT_FRAGMENTS option
  - JFFS2: remove node version 0 warning
  - JFFS2: accept JFFS2 PADDING nodes
  - SXNI855T: add AM29LV800 support
  - SXNI855T: move environment from EEPROM to flash
  - SXNI855T: boot from JFFS2 in NOR or NAND flash

* Patch by Bill Hargen, 11 Aug 2003:
  fixes for I2C on MPC8240
  - fix i2c_write routine
  - fix iprobe command
  - eliminates use of global variables, plus dead code, cleanup.

-CONTENT:

-   i2c2.s
-
-WHAT ARE THESE FILES:
-
-These files contain MPC8240 (Kahlua) I2C
-driver routines. The driver routines are not
-written for any specific operating system.
-They serves the purpose of code sample, and
-jump-start for using the MPC8240 I2C unit.
-
-For the reason of correctness of C language
-syntax, these files are compiled by Metaware
-C compiler and assembler.
-
-ENDIAN NOTATION:
-
-The algorithm is designed for big-endian mode,
-software is responsible for byte swapping.
-
-USAGE:
-
-1. The host system that is running on MPC8240
-   shall link the files listed here. The memory
-   location of driver routines shall take into
-   account of that driver routines need to run
-   in supervisor mode and they process I2C
-   interrupt.
-
-2. The host system is responsible for configuring
-   the MPC8240 including Embedded Utilities Memory
-   Block. All I2C driver functions require the
-   content of Embedded Utilities Memory Block
-   Base Address Register, EUMBBAR, as the first
-   parameter.
-
-3. Before I2C unit of MPC8240 can be used,
-   initialize I2C unit by calling I2C_Init
-   with the corresponding parameters.
-
-   Note that the I2CFDR register shall be written
-   once during the initialization. If it is written
-   in the midst of transers, or after I2C STOPs or
-   REPEAT STATRs, depending on the data written,
-   a long reset time may be encountered.
-
-4. After I2C unit has been successfully initialized,
-   use the Application level API to send data or
-   receive data upon the desired mode, Master or
-   Slave.
-
-5. If the host system is also using the EPIC unit
-   on MPC8240, the system can register the
-   I2C_ISR with the EPIC including other
-   desired resources.
-
-   If the host system does not using the EPIC unit
-   on MPC8240, I2C_Timer_Event function can
-   be called for each desired time interval.
-
-   In both cases, the host system is free to provide
-   its own timer event handler and interrupt service
-   routine.
-
-6. The I2C driver routines contains a set
-   of utilities, Set and Get, for host system
-   to query and modify the desired I2C registers.
-
-7. It is the host system's responsibility of
-   queueing the I2C I/O request. The host
-   system shall check the I2C_ISR return code
-   for I2C I/O status. If I2C_ISR returns
-   I2CBUFFEMPTY or I2CBUFFFULL, it means
-   I2C unit has completed a I/O request
-   stated by the Application API.
-
-8. If the host system has more than one master
-   mode I2C unit I/O requests but doesn't want
-   to be intervented by being addressed as slave,
-   the host system can use the master mode
-   Application API with stop_flag set to 0 in
-   conjunction with is_cnt flag set to 1.
-   The first API call sets both stop_flag and
-   is_cnt to 0, indicating a START condition
-   shall be generated but when the end of
-   transaction is reached, do not generate a
-   STOP condition. Once the host system is
-   informed that the transaction has been
-   completed, the next Application API call
-   shall set is_cnt flag to 1, indicating a
-   repeated START condition shall be generated.
-   The last Application API call shall set
-   stop_flag
-   to 1.
-
-9. The I2C_Timer_Event function containes
-   a user defined function pointer. It
-   serves the purpose of providing the
-   host system a way to use its own event
-   handler instead of the I2C_ISR provided
-   here.
