I had to get up the kernel on two boards (MPC857T and MPC8280)
recently. I use the ELDK3.0 with the kernel 2.4.24 shipped with it.
I had to modify the following files:
arch/ppc/config.in
machine type (my board) added
arch/ppc/boot/simple/embed_config.c
there is a function emebd_config() for every board selected by
#ifdefs; so I added one for my board
arch/ppc/platforms
there are header files for every board; so I added one for my board
include/asm-ppc/mpc8xx.h
#include <platforms/myboard.h> added; selected by #ifdef
This was enough to get the kernel up with a serial i/f.
It may be necessary to modify the ethernet driver a little bit to
adapt it to your pin configuration.
Flash support was no problem for the CFI chips on the boards.
I'm just a newbie too, so don't kill me if there is something missed
or wrong.
HTH,
Oliver
