By default, the ebony code uses -the SPD to initialize the DDR SDRAM control registers. So if the SPD -eeprom is corrupted, U-Boot will never get into ram. Here's how I got -out of this situation: - -0. First, _before_ playing with the i2c utilities, do an 'i2c probe', then -use 'i2c md' to capture the various device contents to a file. Some day -you may be glad you did this ... trust me :-). Otherwise try the -following: - -1. In the include/configs/EBONY.h file find the line that defines -the CONFIG_SPD_EEPROM macro and undefine it. E.g: - -#undef CONFIG_SPD_EEPROM - -This will make the code use default SDRAM control register -settings without using the SPD eeprom. - -2. Rebuild U-Boot - -3. Load the new U-Boot image and reboot ebony. - -4. Repair the SPD eeprom using the 'i2c mm' command. Here's the eeprom -contents that work with the default SO-DIMM that comes with the -ebony board (micron 8VDDT164AG-265A1). Note: these are probably -_not_ the factory settings ... but they work. - -=> i2c md 53 0 10 80 -0000: 80 08 07 0c 0a 01 40 00 04 75 75 00 80 08 00 01 ......@..uu..... -0010: 0e 04 0c 01 02 20 00 a0 75 00 00 50 3c 50 2d 20 ..... ..u..P diff --git a/board/amcc/ebony/config.mk b/board/amcc/ebony/config.mk deleted file mode 100644 index f18b09710d..0000000000 --- a/board/amcc/ebony/config.mk +++ /dev/null @@ -1,16 +0,0 @@ -# -# (C) Copyright 2002 -# Wolfgang Denk, DENX Software Engineering, wd@denx.de. -# -# SPDX-License-Identifier: GPL-2.0+ -# - -PLATFORM_CPPFLAGS += -DCONFIG_440=1 - -ifeq ($(debug),1) -PLATFORM_CPPFLAGS += -DDEBUG -endif - -ifeq ($(dbcr),1) -PLATFORM_CPPFLAGS += -DCONFIG_SYS_INIT_DBCR=0x8cff0000 -endif diff --git a/board/amcc/ebony/ebony.c b/board/amcc/ebony/ebony.c deleted file mode 100644 index eb424489ef..0000000000 --- a/board/amcc/ebony/ebony.c +++ /dev/null @@ -1,151 +0,0 @@ -/* - * Copyright (C) 2002 Scott McNutt - * - * SPDX-License-Identifier: GPL-2.0+ - */ - -#include -#include -#include - -#define BOOT_SMALL_FLASH 32 /* 00100000 */ -#define FLASH_ONBD_N 2 /* 00000010 */ -#define FLASH_SRAM_SEL 1 /* 00000001 */ - -DECLARE_GLOBAL_DATA_PTR;
