Re: walnut configuration

[Peter Barada <pbarada@mail.wm.sps.mot.com>]

Has *anyone* gotten the linuxppc_2_4_devel tree to build for a walnut board?
If so, what did you have to do... I've tried the following:

I've gotten a BK resync of the linuxppc_2_4_devel tree as of today and
attempted to:

1) edit top level makefile to redefine ARCH to ppc, set CROSS_COMPILE
   to my tool prefix
2) make mkproper
3) make walnut_config
4) make oldconfig
5) make dep
6) make

This fails while trying to build head_4xx.S since
CONFIG_PPC601_SYCN_FIX is set in .config when it shouldn't be.


After getting past that, it fails next while trying to compile
ppc4xx_pic.c with:

powerpc-linux-gcc -D__KERNEL__ -I/home/pbarada/work/penguinppc/linuxppc_2_4_devel.export.3/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fomit-frame-pointer -fno-strict-aliasing -fno-common -D__powerpc__ -fsigned-char -msoft-float -pipe -ffixed-r2 -Wno-uninitialized -mmultiple -mstring -mcpu=403    -c -o ppc4xx_pic.o ppc4xx_pic.c

make[1]: *** [ppc4xx_pic.o] Error 1
make[1]: Leaving directory `/home/pbarada/work/penguinppc/linuxppc_2_4_devel.export.3/arch/ppc/kernel'

This is caused by in include/asm-ppc/processor.h, the following needs
to be change from:

#include <asm/mpc8xx.h>

to:

#ifdef CONFIG_4xx
#include <asm/ppc4xx.h>
#endif
#ifdef CONFIG_8xx
#include <asm/mpc8xx.h>
#endif


Now it gets past ppc4xx_pic.c, and now blows up compilling walnut_setup.c
with:

powerpc-linux-gcc -D__KERNEL__ -I/home/pbarada/work/penguinppc/linuxppc_2_4_devel.export.3/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fomit-frame-pointer -fno-strict-aliasing -fno-common -D__powerpc__ -fsigned-char -msoft-float -pipe -ffixed-r2 -Wno-uninitialized -mmultiple -mstring -mcpu=403    -c -o walnut_setup.o walnut_setup.c

At this point I thought I'd ask.
