This -will be done from offset 0x80 with the length of 0x80 bytes. The -following command can be used to store the values here: - -=> setdef de:20:6a:ed:e2:72 de:20:6a:ed:e2:73 AB0001 - - ethaddr eth1addr serial# - -Now those 3 values are stored into the I2C EEPROM. A CRC is added -to make sure that the values get not corrupted. - - -SW-Reset Pushbutton handling: ------------------------------ - -The SW-reset push button is connected to a GPIO input too. This -way U-Boot can "see" how long the SW-reset was pressed, and a -specific action can be taken. Two different actions are supported: - -a) Release after more than 5 seconds and less then 10 seconds: - -> Run POST - - Please note, that the POST test will take a while (approx. 1 min - on the 128MByte board). This is mainly due to the system memory - test. - -b) Release after more than 10 seconds: - -> Restore factory default settings - - The factory default values are restored. The default environment - variables are restored (ipaddr, serverip...) and the board - specific values (ethaddr, eth1addr and serial#) are restored - to the environment from the I2C EEPROM. Also a bootline parameter - is added to the Linux bootline to signal the Linux kernel upon - the next startup, that the factory defaults should be restored. - -The command to check this sw-reset status and act accordingly is - -=> chkreset - -This command is added to the default "bootcmd", so that it is called -automatically upon startup. - -Also, the 2 LED's are used to indicate the current status of this -command (time passed since pushing the button). When the POST test -will be run, the green LED will be switched off, and when the -factory restore will be initiated, the reg LED will be switched off. - - -Loggin of POST results: ------------------------ - -The results of the POST tests are logged in a logbuffer located at the end -of the onboard memory. It can be accessed with the U-Boot command "log": - -=> log show -<4>POST memory PASSED -<4>POST cache PASSED -<4>POST cpu PASSED -<4>POST uart PASSED -<4>POST ethernet PASSED - -The DENX Linux kernel tree has support for this log buffer included. Exactly -this buffer is used for logging of all kernel messages too. By enabling the -compile time option "CONFIG_LOGBUFFER" this support is enabled. This way you -can access the U-Boot log messages from Linux too. - -2007-08-10, Stefan Roese <sr@denx.de> diff --git a/board/zeus/update.c b/board/zeus/update.c deleted file mode 100644 index ac738ef2ab..0000000000 --- a/board/zeus/update.c +++ /dev/null @@ -1,89 +0,0 @@ -/* - * (C) Copyright 2007 - * Stefan Roese, DENX Software Engineering, sr@denx.de. - * - * SPDX-License-Identifier: GPL-2.0+ - */ - -#include <config.h> -#include <common.h> -#include <command.h> -#include <asm/processor.h> -#include <asm/io.h> -#include <asm/ppc4xx-gpio.h> -#include <i2c.h> - -#if defined(CONFIG_ZEUS) - -u8 buf_zeus_ce[] = { -/*00 01 02 03 04 05 06 07 */ - 0x05, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, -/*08 09 0a 0b 0c 0d 0e 0f */ - 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, -/*10 11 12 13 14 15 16 17 */ - 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, -/*18 19 1a 1b 1c 1d 1e 1f */ - 0x00, 0xc0, 0x50, 0x12, 0x72, 0x3e, 0x00, 0x00 }; - -u8 buf_zeus_pe[] = { - -/* CPU_CLOCK_DIV 1 = 00 - CPU_PLB_FREQ_DIV 3 = 10 - OPB_PLB_FREQ_DIV 2 = 01 - EBC_PLB_FREQ_DIV 2 = 00 - MAL_PLB_FREQ_DIV 1 = 00 - PCI_PLB_FRQ_DIV 3 = 10 - PLL_PLLOUTA = IS SET - PLL_OPERATING = IS NOT SET - PLL_FDB_MUL 10 = 1010 - PLL_FWD_DIV_A 3 = 101 - PLL_FWD_DIV_B 3 = 101 - TUNE = 0x2be */ -/*00 01 02 03 04 05 06 07 */ - 0x05, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, -/*08 09 0a 0b 0c 0d 0e 0f */ - 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, -/*10 11 12 13 14 15 16 17 */ - 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, -/*18 19 1a 1b 1c 1d 1e 1f */ - 0x00, 0x60, 0x68, 0x2d, 0x42, 0xbe, 0x00, 0x00 }; - -static int update_boot_eeprom(void) -{ - u32 len = 0x20; - u8 chip = CONFIG_SYS_I2C_EEPROM_ADDR; - u8 *pbuf; - u8 base; - int i; - - if (in_be32((void *)GPIO0_IR) & GPIO_VAL(CONFIG_SYS_GPIO_ZEUS_PE)) { - pbuf = buf_zeus_pe; - base = 0x40; - } else { - pbuf = buf_zeus_ce; - base = 0x00; - } - - for (i = 0; i < len; i++, base++) { - if (i2c_write(chip, base, 1, &pbuf[i], 1) != 0) { - printf("i2c_write fail\n"); - return 1; - } - udelay(11000); - } - - return 0; -} - -int do_update_boot_eeprom(cmd_tbl_t* cmdtp, int flag, int argc, char * const argv[]) -{ - return update_boot_eeprom(); -} - -U_BOOT_CMD ( - update_boot_eeprom, 1, 1, do_update_boot_eeprom, - "update boot eeprom content", - "" -); - -#endif diff --git a/board/zeus/zeus.c b/board/zeus/zeus.c deleted file mode 100644 index e2b12f677e..0000000000 --- a/board/zeus/zeus.c +++ /dev/null @@ -1,410 +0,0 @@ -/* - * (C) Copyright 2007 - * Stefan Roese, DENX Software Engineering, sr@denx.de. - * - * SPDX-License-Identifier: GPL-2.0+ - */ - -#include <common.h> -#include <command.h> -#include <malloc.h> -#include <environment.h> -#include <logbuff.h> -#include <post.h> - -#include <asm/processor.h> -#include <asm/io.h> -#include <asm/ppc4xx-gpio.h> - -DECLARE_GLOBAL_DATA_PTR; - -#define REBOOT_MAGIC 0x07081967 -#define REBOOT_NOP 0x00000000 -#define REBOOT_DO_POST 0x00000001 - -extern flash_info_t flash_info[CONFIG_SYS_MAX_FLASH_BANKS]; /* info for FLASH chips */ - -ulong flash_get_size(ulong base, int banknum); -void env_crc_update(void); - -static u32 start_time; - -int board_early_init_f(void) -{ - mtdcr(UIC0SR, 0xFFFFFFFF); /* clear all ints */ - mtdcr(UIC0ER, 0x00000000); /* disable all ints */ - mtdcr(UIC0CR, 0x00000000); - mtdcr(UIC0PR, 0xFFFF7F00); /* set int polarities */ - mtdcr(UIC0TR, 0x00000000); /* set int trigger levels */ - mtdcr(UIC0SR, 0xFFFFFFFF); /* clear all ints */ - mtdcr(UIC0VCR, 0x00000001); /* set vect base=0,INT0 highest priority */ - - /* - * Configure CPC0_PCI to enable PerWE as output - */ - mtdcr(CPC0_PCI, CPC0_PCI_SPE); - - return 0; -} - -int misc_init_r(void) -{ - u32 pbcr; - int size_val = 0; - u32 post_magic; - u32 post_val; - - post_magic = in_be32((void *)CONFIG_SYS_POST_MAGIC); - post_val = in_be32((void *)CONFIG_SYS_POST_VAL); - if ((post_magic == REBOOT_MAGIC) && (post_val == REBOOT_DO_POST)) { - /* - * Set special bootline bootparameter to pass this POST boot - * mode to Linux to reset the username/password - */ - setenv("addmisc", "setenv bootargs \\${bootargs} factory_reset=yes"); - - /* - * Normally don't run POST tests, only when enabled - * via the sw-reset button.
