This is my attempt to port U-Boot to the i386 platform. Thiswork was sponsored by my emplyer, Omicron Ceti AB. http://www.omicron.seIt is currently capable of booting a linux bzImage from flash onthe AMD SC520 CDP platform.It was originally based on PPCBoot taken from the CVS October 28 2002.To compile:1) Unpack the source tree, either from the complete tarball or   from the virgin snapshot + the patch2) Configure the source   $ make sc520_cdp_comfig   $ makeTo use this code on the CDP:1) Make a suitable kernel, I used 2.4.19 with the mtd-support updated   from the MTD CVS and a patch to allow root=/dev/mtdblock1 which I   included at the end of this file.   The following options in the MTD section might be useful:   CONFIG_MTD_PHYSMAP=y   CONFIG_MTD_PHYSMAP_START=38100000   CONFIG_MTD_PHYSMAP_LEN=7a0000   CONFIG_MTD_PHYSMAP_BUSWIDTH=22) Program it in to the CDP flashbank with remon   u-boot.bin should be programmed att offset 0x7e000 and the kernel at   offset 0. If you want to use a jffs2 root file system (not included here),   it should be  programmed to offset 0x100000.   remon> z   remon> yi   remon> ns u-boot.bin 7e0000   remon> ns bzImage 0   remon> ns image.jffs2 1000003) Connect a terminal to the 25pin serial port at 9600bps, and start the CDP.   remon> z   remon> g4) U-Boot should output some message and a prompt on the terminal, to   start the kernel issue the following command:   BOOT> bootm5) The kernel should boot, and mount the root filesystem if present.We hope you find this stuff usefulDaniel Engstr鰉, Omicron Ceti AB, daniel@omicron.se--- linux-2.4.19-orig/init/do_mounts.c	Sat Aug  3 02:39:46 2002+++ linux-2.4.19/init/do_mounts.c	Mon Sep 23 16:21:33 2002@@ -224,6 +224,14 @@ 	{ "ftlc", 0x2c10 }, 	{ "ftld", 0x2c18 }, 	{ "mtdblock", 0x1f00 },+	{ "mtdblock0", 0x1f00 },+	{ "mtdblock1", 0x1f01 },+	{ "mtdblock2", 0x1f02 },+	{ "mtdblock3", 0x1f03 },+	{ "mtdblock4", 0x1f04 },+	{ "mtdblock5", 0x1f05 },+	{ "mtdblock6", 0x1f06 },+	{ "mtdblock7", 0x1f07 }, 	{ NULL, 0 } };-------------------
