booting HardHat on IBM 405GP

[Zehetbauer Thomas]

Hi!

My company is going to develop an embedded solution based on a IBM 406GP
processor.
We are in early development right now and I am trying to boot linux on a
> IBM 25 EB 405 P4 WIN WAL 00
evaluation kit (this is the information on the bill of delivery).

Attempting to debug I've found linux/arch/ppc/boot/tree/main.c:start to
be the first function executed.
At the very last step this function calls
>    (*(void (*)())sa)(&board_info,
>                      initrd_start,
>                      initrd_start + initrd_size,
>                      cmdline,
>                      cmdline + strlen(cmdline));
and I can't find where execution goes on.

Any help is greatly appreciated.

TIA
Tom

PS: Does someone know how to determine the board's revision number?
