In U-Boot werden die vom -Keyboard-Controller gelesenen Daten hexadezimal codiert in der auto- -matisch angelegten Environment-Variablen "keybd" übergeben. Ist kei- -ne Taste gedrückt worden, steht dort: - - keybd=000000000000000000 - -Der decodierte Tastencode ("keybd") kann mit den "bootargs" an den -Linux-Kernel übergeben und dort z.

Tastenkombination erkannt, so wird -in U-Boot noch vor dem Start des "Countdown" und somit vor jedem an- -deren Kommando der Inhalt einer dieser Taste bzw. 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/lwmon/flash.c b/board/lwmon/flash.c deleted file mode 100644 index cb60c41..0000000 --- a/board/lwmon/flash.c +++ /dev/null @@ -1,632 +0,0 @@ -/* - * (C) Copyright 2001 - * Wolfgang Denk, DENX Software Engineering, wd@denx.de. - * - * SPDX-License-Identifier: GPL-2.0+ - */ - -/* #define DEBUG */ - -#include <common.h> -#include <mpc8xx.h> - -#if defined(CONFIG_ENV_IS_IN_FLASH) -# ifndef CONFIG_ENV_ADDR -# define CONFIG_ENV_ADDR (CONFIG_SYS_FLASH_BASE + CONFIG_ENV_OFFSET) -# endif -# ifndef CONFIG_ENV_SIZE -# define CONFIG_ENV_SIZE CONFIG_ENV_SECT_SIZE -# endif -# ifndef CONFIG_ENV_SECT_SIZE -# define CONFIG_ENV_SECT_SIZE CONFIG_ENV_SIZE -# endif -#endif - -/*---------------------------------------------------------------------*/ - -flash_info_t flash_info[CONFIG_SYS_MAX_FLASH_BANKS]; /* info for FLASH chips */ - -/*----------------------------------------------------------------------- - * Functions - */ -static ulong flash_get_size (vu_long *addr, flash_info_t *info); -static int write_data (flash_info_t *info, ulong dest, ulong data); -#ifdef CONFIG_SYS_FLASH_USE_BUFFER_WRITE -static int write_data_buf (flash_info_t * info, ulong dest, uchar * cp, int len); -#endif -static void flash_get_offsets (ulong base, flash_info_t *info); - -/*----------------------------------------------------------------------- - */ - -unsigned long flash_init (void) -{ - volatile immap_t *immap = (immap_t *)CONFIG_SYS_IMMR; - volatile memctl8xx_t *memctl = &immap->im_memctl; - unsigned long size_b0, size_b1; - int i; - - /* Init: no FLASHes known */ - for (i=0; i<CONFIG_SYS_MAX_FLASH_BANKS; ++i) { - flash_info[i].flash_id = FLASH_UNKNOWN; - } - - /* Static FLASH Bank configuration here - FIXME XXX */ - - debug ("\n## Get flash bank 1 size @ 0x%08x\n",FLASH_BASE0_PRELIM); - - size_b0 = flash_get_size((vu_long *)FLASH_BASE0_PRELIM, &flash_info[0]); - - if (flash_info[0].flash_id == FLASH_UNKNOWN) { - printf ("## Unknown FLASH on Bank 0: " - "ID 0x%lx, Size = 0x%08lx = %ld MB\n", - flash_info[0].flash_id, - size_b0, size_b0<<20); - } - - debug ("## Get flash bank 2 size @ 0x%08x\n",FLASH_BASE1_PRELIM); - - size_b1 = flash_get_size((vu_long *)FLASH_BASE1_PRELIM, &flash_info[1]); - - debug ("## Prelim.
