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

i386 port missing features:
* i386 cleaness (wbinvld is 486+ ... )
* Pentium TSC timer/udelay
* setup the BIOS data area and BIOS equipment word to reflect machine config.
* Make reset work (from Linux and from the boot prompt)
* DMA, FDC, RTC, KBC initialization
* split of part of arch/i386/cpu/interrupt.c to cpu/i385/entry.c?
* re-entry of protected mode from real mode, should be added to realmode_switch.S
(and used by INT 10h and INT 16h handlers for console I/O during early
linux boot...)
* missing functions in arch/i386/lib and arch/i386/cpu
* speaker beep interface
SC520 missing features:
* Watchdog
* SC520 timer/udelay
* SC520 3rd PIC
* SC520 ICE serial
* SC520 MMCR reset
SC520 CDP board support missing features:
* environment in sram
SC520 CDP board support bugs:
* SPI EEPROM support does not work
* 0x680 LEDS dos not work for me
* is it possible to make both the internal serial ports and the
ports on the sio work at the same time?
