Yes, I'm sorry for the confusion - I needed to add a new board, not a
new arch - arch is PXA25x of course. I have a dev board here similar to
lubbock, and the latest kernel for it by its manifacturer was 2.6.7. I
need at least 2.6.10 for my current project, but this board has an ASIX
AX88796 controller which does not have build in kernel support, so I
have to use the driver from the 2.6.7 kernel. Anyway are you certain
that this are all the step required to add a new board because a
followed them exactly but with the new board the kernel won't boot:
ARMboot 1.2.0 by Voipac <www.voipac.com> (Nov 24 2004 - 14:29:51)
ARMboot code: a1000000 -> a1019034
CPU: Intel XScale-PXA255 (ARM 5TE) revision A0
Clock: Mem=99.53MHz (*27), Run=199.07MHz (*2), Turbo=199.07MHz
(*1.0,inactive)
DRAM Configuration:
Bank #0: a0000000 16 MB
Bank #1: a4000000 0 KB
Bank #2: a8000000 0 KB
Bank #3: ac000000 0 KB
Flash: 16 MB
Hit any key to stop autoboot: 0
Starting Linux kernel image at 0x40000
Architecture type: 89
Command line: mem=16M root=/dev/mtdblock2 rootfstype=jffs2
console=ttyS0,115200
Uncompressing
Linux......................................................... done,
booting the kernel.
And that is all. The two boards are very simillar, I had to change but a
few things in lubbock.c to create the new voipac.c. Can someone take a
look at their source files (there quite small) and tell me if has some
idea what could be wrong. This 2.6.11 kernel works file with lubbock.c...

Somehow I got the kernel booting, but now I have some problems with
lubbock-flash.c and since I noticed you have written it I'd like to ask
for your help.
Lubbock configured to boot from ROM (bank 0)
Probing Lubbock Boot ROM at physical address 0x00000000 (16-bit bankwidth)

Lubbock Application Flash is absent. Skipping

Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(31,2)
I haven't changed the mappings at all. With lubbock board it works OK,
but with mine - kernel panic. Root fs is of course at the correct
address. I have edited appropriately(or at least I think so) all the
Kconfig and Makefiles. And the difference between lubbock.c and voipac.c
- as you can see prost my previous letter is pretty much minimal. I'm
out of ideas and would really appreciate any help that I can get.
TIA,
Bozhidar
