Tastenkombination +zugeordneten Environment-Variablen ausführen. + + +Die Environment-Variable "magic_keys" wird als Liste von Zeichen ver- +standen, die als Suffix an den Namen "key_magic" angefügt werden und +so die Namen der Environment-Variablen definieren, mit denen die +Tasten (-kombinationen) festgelegt werden: + +Ist "magic_keys" NICHT definiert, so wird nur die in der Environment- +Variablen "key_magic" codierte Tasten (-kombination) geprüft, und +ggf. der Inhalt der Environment-Variablen "key_cmd" ausgeführt (ge- +nauer: der Inhalt von "key_cmd" wird der Variablen "preboot" zugewie- +sen, die ausgeführt wird, unmittelbar bevor die interaktive Kommando- +interpretation beginnt). + +Enthält "magic_keys" z. B. die Zeichenkette "0123CB*", so werden +nacheinander folgende Aktionen ausgeführt: + + prüfe Tastencode ggf. führe aus Kommando + in Variable in Variable + ----------------------------------- + key_magic0 ==> key_cmd0 + key_magic1 ==> key_cmd1 + key_magic2 ==> key_cmd2 + key_magic3 ==> key_cmd3 + key_magicC ==> key_cmdC + key_magicB ==> key_cmdB + key_magicA ==> key_cmdA + key_magic* ==> key_cmd* + +Hinweis: sobald ein aktivierter Tastencode erkannt wurde, wird die +Bearbeitung abgebrochen; es wird daher höchstens eines der definier- +ten Kommandos ausgeführt, wobei die Priorität durch die Suchreihen- +folge festgelegt wird, also durch die Reihenfolge der Zeichen in der +Varuiablen "magic_keys". + + +Die Codierung der Tasten, die beim Booten gedrückt werden müssen, um +eine Funktion auszulösen, erfolgt nach der Tastaturtabelle. + +Die Definitionen + + => setenv key_magic0 3a+3b + => setenv key_cmd0 setenv bootdelay 30 + +bedeuten dementsprechend, daß die Tasten mit den Codes 0x3A (Taste +"F1") und 0x3B (Taste "F2") gleichzeitig gedrückt werden müssen. Sie +können dort eine beliebige Tastenkombination eintragen (jeweils 2 +Zeichen für die Hex-Codes der Tasten, und '+' als Trennzeichen). + +Wird die eingestellte Tastenkombination erkannt, so wird in U-Boot +noch vor dem Start des "Countdown" und somit vor jedem anderen Kom- +mando das angebene Kommando ausgeführt und somit ein langes Boot- +Delay eingetragen. + +Praktisch könnten Sie also in U-Boot "bootdelay" auf 0 setzen und +somit stets ohne jede User-Interaktion automatisch booten, außer, +wenn die beiden Tasten "F1" und "F2" beim Booten gedrückt werden: +dann würde ein Boot-Delay von 30 Sekunden eingefügt. + + +Hinweis: dem Zeichen '#' kommt innerhalb von "magic_keys" eine beson- +dere Bedeutung zu: die dadurch definierte Key-Sequenz schaltet den +Monitor in den "Debug-Modus" - das bedeutet zunächst, daß alle weite- +ren Meldungen von U-Boot über das LCD-Display ausgegeben werden; +außerdem kann man durch das mit dieser Tastenkombination verknüpfte +Kommando z. B. die Linux-Bootmeldungen ebenfalls auf das LCD-Display +legen, so daß der Boot-Vorgang direkt und ohne weitere Hilfsmittel +analysiert werden kann. + +Beispiel: + +In U-Boot werden folgende Environment-Variablen gesetzt und abgespei- +chert: + +(1) => setenv magic_keys 01234#X +(2) => setenv key_cmd# setenv addfb setenv bootargs \\$(bootargs) console=tty0 console=ttyS1,\\$(baudrate) +(3) => setenv nfsargs setenv bootargs root=/dev/nfs rw nfsroot=\$(serverip):\$(rootpath) +(4) => setenv addip setenv bootargs \$(bootargs) ip=\$(ipaddr):\$(serverip):\$(gatewayip):\$(netmask):\$(hostname)::off panic=1 +(5) => setenv addfb setenv bootargs \$(bootargs) console=ttyS1,\$(baudrate) +(6) => setenv bootcmd bootp\;run nfsargs\;run addip\;run addfb\;bootm + +Hierbei wird die Linux Commandline (in der Variablen "bootargs") im +Boot-Kommando "bootcmd" (6) schrittweise zusammengesetzt: zunächst +werden die für Root-Filesystem über NFS erforderlichen Optionen ge- +setzt ("run nfsargs", vgl. (3)), dann die Netzwerkkonfiguration an- +gefügt ("run addip", vgl. (4)), und schließlich die Systemconsole +definiert ("run addfb"). + +Dabei wird im Normalfall die Definition (5) verwendt; wurde aller- +dings beim Reset die entsprechende Taste gedrückt gehalten, so wird +diese Definition bei der Ausführung des in (2) definierten Kommandos +überschrieben, so daß Linux die Bootmeldungen auch über das Frame- +buffer-Device (=LCD-Display) ausgibt. + +Beachten Sie die Verdoppelung der '\'-Escapes in der Definition von +"key_cmd#" - diese ist erforderlich, weil der String _zweimal_ inter- +pretiert wird: das erste Mal bei der Eingabe von "key_cmd#", das +zweite Mal, wenn der String (als Inhalt von "preboot") ausgeführt +wird. diff --git a/board/mousse/flash.c b/board/mousse/flash.c new file mode 100644 index 000000000..3c4a802da --- /dev/null +++ b/board/mousse/flash.c @@ -0,0 +1,944 @@ +/* + * MOUSSE/MPC8240 Board definitions. + * Flash Routines for MOUSSE onboard AMD29LV106DB devices + * + * (C) Copyright 2000 + * Marius Groeger <mgroeger@sysgo.de> + * Sysgo Real-Time Solutions, GmbH <www.elinos.com> + * + * (C) Copyright 2000 + * Wolfgang Denk, DENX Software Engineering, wd@denx.de. + * + * (C) Copyright 1999, by Curt McDowell, 08-06-99, Broadcom Corp. + * (C) Copyright 2001, James Dougherty, 07/18/01, Broadcom Corp. + * + * See file CREDITS for list of people who contributed to this + * project. + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License as + * published by the Free Software Foundation; either version 2 of + * the License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

See it for details. They are: + + bootdelay + bootcmd + CONFIG_BOOTDELAY + CONFIG_BOOTCOMMAND + +Some additional options that make autoboot safer in a production +product are documented here. + +Why use them? +------------- + +The basic autoboot feature allows a system to automatically boot to +the real application (such as Linux) without a user having to enter +any commands. If any key is pressed before the boot delay time +expires, U-Boot stops the autoboot process, gives a U-Boot prompt +and waits forever for a command. That's a good thing if you pressed a +key because you wanted to get the prompt. + +It's not so good if the key press was a stray character on the +console serial port, say because a user who knows nothing about +U-Boot pressed a key before the system had time to boot. It's even +worse on an embedded product that doesn't have a console during +normal use. The modem plugged into that console port sends a +character at the wrong time and the system hangs, with no clue as to +why it isn't working. + +You might want the system to autoboot to recover after an external +configuration program stops autoboot. If the configuration program +dies or loses its connection (modems can disconnect at the worst +time) U-Boot will patiently wait forever for it to finish. + +These additional configuration options can help provide a system that +boots when it should, but still allows access to U-Boot. + +What they do +------------ + + CONFIG_BOOT_RETRY_TIME + CONFIG_BOOT_RETRY_MIN + + bootretry environment variable + + These options determine what happens after autoboot is + stopped and U-Boot is waiting for commands. + + CONFIG_BOOT_RETRY_TIME must be defined to enable the boot + retry feature. If the environment variable 'bootretry' is + found then its value is used, otherwise the retry timeout is + CONFIG_BOOT_RETRY_TIME. CONFIG_BOOT_RETRY_MIN is optional and + defaults to CONFIG_BOOT_RETRY_TIME. All times are in seconds. + + If the retry timeout is negative, the U-Boot command prompt + never times out. Otherwise it is forced to be at least + CONFIG_BOOT_RETRY_MIN seconds. If no valid U-Boot command is + entered before the specified time the boot delay sequence is + restarted. Each command that U-Boot executes restarts the + timeout. + + If CONFIG_BOOT_RETRY_TIME < 0 the feature is there, but + doesn't do anything unless the environment variable + 'bootretry' is >= 0. + + CONFIG_AUTOBOOT_KEYED + CONFIG_AUTOBOOT_PROMPT + CONFIG_AUTOBOOT_DELAY_STR + CONFIG_AUTOBOOT_STOP_STR + CONFIG_AUTOBOOT_DELAY_STR2 + CONFIG_AUTOBOOT_STOP_STR2 + + bootdelaykey environment variable + bootstopkey environment variable + bootdelaykey2 environment variable + bootstopkey2 environment variable + + These options give more control over stopping autoboot. When + they are used a specific character or string is required to + stop or delay autoboot. + + Define CONFIG_AUTOBOOT_KEYED (no value required) to enable + this group of options. CONFIG_AUTOBOOT_DELAY_STR, + CONFIG_AUTOBOOT_STOP_STR or both should be specified (or + specified by the corresponding environment variable), + otherwise there is no way to stop autoboot. + + CONFIG_AUTOBOOT_PROMPT is displayed before the boot delay + selected by CONFIG_BOOTDELAY starts. If it is not defined + there is no output indicating that autoboot is in progress. + If "%d" is included, it is replaced by the number of seconds + remaining before autoboot will start, but it does not count + down the seconds. "autoboot in %d seconds\n" is a reasonable + prompt. + + If CONFIG_AUTOBOOT_DELAY_STR or bootdelaykey is specified and + this string is received from console input before autoboot + starts booting, U-Boot gives a command prompt. The U-Boot + prompt will time out if CONFIG_BOOT_RETRY_TIME is used, + otherwise it never times out. + + If CONFIG_AUTOBOOT_STOP_STR or bootstopkey is specified and + this string is received from console input before autoboot + starts booting, U-Boot gives a command prompt. The U-Boot + prompt never times out, even if CONFIG_BOOT_RETRY_TIME is + used. + + The string recognition is not very sophisticated. If a + partial match is detected, the first non-matching character + is checked to see if starts a new match. There is no check + for a shorter partial match, so it's best if the first + character of a key string does not appear in the rest of the + string. + + Using the CONFIG_AUTOBOOT_DELAY_STR2 / bootdelaykey2 and/or + CONFIG_AUTOBOOT_STOP_STR2 / bootstopkey #defines and/or + environment variables you can specify a second, alternate + string (which allows you to haw two "password" strings). + + CONFIG_ZERO_BOOTDELAY_CHECK + + If this option is defined, you can stop the autoboot process + by hitting a key even in that case when "bootdelay" has been + set to 0. You can set "bootdelay" to a negative value to + prevent the check for console input. + + CONFIG_RESET_TO_RETRY + + (Only effective when CONFIG_BOOT_RETRY_TIME is also set) + After the countdown timed out, the board will be reset to restart + again. + diff --git a/doc/README.console b/doc/README.console new file mode 100644 index 000000000..6d477df75 --- /dev/null +++ b/doc/README.console @@ -0,0 +1,118 @@ +/* + * (C) Copyright 2000 + * Paolo Scaffardi, AIRVENT SAM s.p.a - RIMINI(ITALY), arsenio@tin.it + * + * See file CREDITS for list of people who contributed to this + * project. + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License as + * published by the Free Software Foundation; either version 2 of + * the License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

When U-Boot +relocates itself to RAM, all console drivers are initialized (they +will register all detected console devices to the system for further +use). + +If not defined in the environment, the first input device is assigned +to the 'stdin' file, the first output one to 'stdout' and 'stderr'. + +You can use the command "coninfo" to see all registered console +devices and their flags. You can assign a standard file (stdin, +stdout or stderr) to any device you see in that list simply by +assigning its name to the corresponding environment variable. For +example: + + setenv stdin wl_kbd <- To use the wireless keyboard + setenv stdout video <- To use the video console + +Do a simple "saveenv" to save the console settings in the environment +and get them working on the next startup, too. + +HOW CAN I USE STANDARD FILE INTO THE SOURCES? +--------------------------------------------- + +You can use the following functions to access the console: + +* STDOUT: + putc (to put a char to stdout) + puts (to put a string to stdout) + printf (to format and put a string to stdout) + +* STDIN: + tstc (to test for the presence of a char in stdin) + getc (to get a char from stdin) + +* STDERR: + eputc (to put a char to stderr) + eputs (to put a string to stderr) + eprintf (to format and put a string to stderr) + +* FILE (can be 'stdin', 'stdout', 'stderr'): + fputc (like putc but redirected to a file) + fputs (like puts but redirected to a file) + fprintf (like printf but redirected to a file) + ftstc (like tstc but redirected to a file) + fgetc (like getc but redirected to a file) + +Remember that all FILE-related functions CANNOT be used before +U-Boot relocation (done in 'board_init_r' in common/board.c). + +HOW CAN I USE STANDARD FILE INTO APPLICATIONS? +---------------------------------------------- + +Use the 'bd_mon_fnc' field of the bd_t structure passed to the +application to do everything you want with the console. + +But REMEMBER that that will work only if you have not overwritten any +U-Boot code while loading (or uncompressing) the image of your +application. + +For example, you won't get the console stuff running in the Linux +kernel because the kernel overwrites U-Boot before running. Only +some parameters like the framebuffer descriptors are passed to the +kernel in the high memory area to let the applications (the kernel) +use the framebuffers initialized by U-Boot. + +SUPPORTED DRIVERS +----------------- + +Working drivers: + + serial (architecture dependent serial stuff) + video (mpc8xx video controller) + +Work in progress: + + wl_kbd (Wireless 4PPM keyboard) + +Waiting for volounteers: + + lcd (mpc8xx lcd controller; to ) + +TESTED CONFIGURATIONS +--------------------- + +The driver has been tested with the following configurations (see +CREDITS for other contact informations): + +- MPC823FADS with AD7176 on a PAL TV (YCbYCr) - arsenio@tin.it +- GENIETV with AD7177 on a PAL TV (YCbYCr) - arsenio@tin.it diff --git a/drivers/bcm570x.c b/drivers/bcm570x.c new file mode 100644 index 000000000..a88880ad3 --- /dev/null +++ b/drivers/bcm570x.c @@ -0,0 +1,1709 @@ +/* + * Broadcom BCM570x Ethernet Driver for U-Boot. + * Support 5701, 5702, 5703, and 5704.
