-This is my attempt to port U-Boot to the i386 platform. This
-work was sponsored by my emplyer, Omicron Ceti AB. http://www.omicron.se
-
-It is currently capable of booting a linux bzImage from flash on
-the 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 patch
-
-2) Configure the source
- $ make sc520_cdp_comfig
- $ make
-
-To 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=2
-
-
-2) 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 100000
-
-3) Connect a terminal to the 25pin serial port at 9600bps, and start the CDP.
-
- remon> z
- remon> g
-
-4) U-Boot should output some message and a prompt on the terminal, to
- start the kernel issue the following command:
-
- BOOT> bootm
-
-5) The kernel should boot, and mount the root filesystem if present.
-
-We hope you find this stuff useful
