linux-2.4 & 405gp & other stuff

Hello everyone,
I've tried to compile linux-2.4 kernel (I tried with sources from
kernel.org and with sources from denx.de) but it wasn't successful.
Error output was:
------------------------------------------------------------------------
    {standard input}: Assembler messages:
    {standard input}:85: Error: unsupported relocation type
    {standard input}:86: Error: unsupported relocation type
    {standard input}:113: Error: unsupported relocation type

    {standard input}:147: Error: unsupported relocation type

    `/usr/src/linux-2.4.4-2001-05-12/arch/ppc/kernel'
    make: *** [_dir_arch/ppc/kernel] Error 2
------------------------------------------------------------------------

Kernel was configured for PPC 4xx, Oak Machine type - it had included
only parallel port, serial console, initrd, ide... really 'bare' kernel.

As I could see problem lies in {srcdir}/arch/ppc/kernel/ppc4xx_pic.c (as
obvious :-) - in functions to initialize 405gp interrupt stuff - is
this part (ppc405_uic_enable(), ppc405_uic_disable(),...) implemented
anywhere? I didn't find them in any new sources...
Is there any other way to compile kernel for 405gp? I've got custom made
board, not any of evaluation boards.

Next question I have is: What exactly is 'Machine type' in Platform
support in kernel configuration? What are 'oak' and 'walnut'? Is this
like description of board?

One more question (yeah I know - I'm bugging - sorry :-)
IBM 405gp has included ethernet controller - are there any drivers for
it?

Thank you in advance...

Regards, Jure

Probably not.  You need to use the latest 2_4_devel sources from
BitKeeper or one of the CVS/rsync sites.  See penguinppc.org for details.

Kernel was configured for PPC 4xx, Oak Machine type - it had included
only parallel port, serial console, initrd, ide... really 'bare' kernel.

That's hardly a "bare" kernel......A serial port with an attached
initrd ram disk is a "bare" kernel.  You have selected nearly everything
that is supported.  I'm not sure if Oak will even run properly.  We
have been using Tivo as the 403 test platform.

Ummm....yeah.  The Oak is a 403GCX IBM reference board.  The Walnut
is an IBM 405GP reference board.

it?

Yep.

Oak doesn't compile anymore.

It did not long ago.......don't you have a board for testing so
you can make the changes we need :-)?

Well, not in my office.  If we ever find a working 10base2<->10baseT
converter, maybe we have a chance to keep the Oak code up to date:)
