Status on 403 (Oak) support

I'm trying to run linux on a board with a 403GCX processor on it. I ran into
an error while trying to compile the kernel as follows:

{standard input}: Assembler messages:
{standard input}:83: Error: unsupported relocation type
{standard input}:84: Error: unsupported relocation type
{standard input}:111: Error: unsupported relocation type
{standard input}:128: Error: unsupported relocation type
{standard input}:145: Error: unsupported relocation type
{standard input}:149: Error: unsupported relocation type
{standard input}:64: Error: unsupported relocation type
make[1]: *** [ppc4xx_pic.o] Error 1
make[1]: Leaving directory `/d/ctemp/src/src-linuxppc_2_4/arch/ppc/kernel'
make: *** [_dir_arch/ppc/kernel] Error 2

While searching the archives I found a thread which mentioned that that
kernel no longer compiles for the 403 processor and there was no mention of
a solution to the problem. Which version of the kernel should work on the
403GCX? Thanks for your help.

Yes, when I merged the latest bunch of 405GP changes I did break
some of the 403 support.  Now that 405 and Walnut are working,
I can apply some patches courtesy of Tivo and Mark Hatle that will
allow 403GCX support again.  Just hang on for a couple of days while
we sort this out again.

Thanks.

It's in pretty bad shape right now.  If you are interested in helping, I
have some initial patches that fix simple 403 vs 405 differences.

To figure this out we need to know which instructions the assembler
was trying to assemble.

To do this attempt to build the kernel, and when it fails, cd to
arch/ppc/kernel, paste in the command line that was used to compile
ppc4xx_pic.o, and replace the '-c -o ppc4xx_pic.o' with '-S'.

Then open up ppc4xx_pic.s in an editor, and pull out the
instruction(or directives) at lines 83,84,111,128,145,149 and 64, and
send them to the list.

From there we might have a clue what went wrong.  Better yet, add in

the source code lines(by reading the third number in the nearest
.stabn directive preceding the line that generats the 'unsupported
relocation type').

To me, it's very clear :-).  It was trying to use SPRG4-7 that
don't exist on the 403.....

Uh, yeah, that's crystal clear :-)

The point I tried to make is that assembler errors like that are
impossible to figure out without having the context that caused
it(command line, assembler instructions, stabn numbers, etc).
