This problem seems to have been caused by an incorrectly configured gcc
cross-compiler.    Originally the compiler was built to target
powerpc-unknown-eabi.

The compiler was rebuilt to target powerpc-linux, and the problem was
solved, (however I have not had time to download the image to an MBX board
and actually see it run as of yet.)

Thanks to all that helped.

Wolfgang,

Thank you for the reply....

I was able to perform the following functions

make mbx_config
make oldconfig
make dep
make zImage

Using make zImage, the kernel itself would build, but I got the following
errors when attempting to link the original boot code.

-------
powerpc-eabi-objcopy -O elf32-powerpc \
        --add-section=.image=../images/vmlinux.gz \
        --set-section-flags=.image=contents,alloc,load,readonly,data \
        ../common/dummy.o image.o

image.o

Could this error be related to an incorrectly built cross-compiler?

Using

some information that I found on the web, I build the ppc cross compiler,

as

ppc-unknown-eabi,  which I interpret to mean ppc eabi on unknown O.S.
Should I have built the cross-compiler as ppc-linux-eabi?

I have not yet tried the 'make pImage' build yet, however I have noticed
that 'make pImage' command can not be performed at the Top Level directory
with the standard makefile.  In order to run it I have to export TOPDIR to
be the linux ppc source directory, and then CD to the arch/ppc/boot
directory first.  I will give more details on this once I have given it a
try.

It seems your kernel configuration is broken. You better restart with
the default configuration fro the  MBX  board;  check  that  this  is
compiling fine, and then start modifying according to your needs:

$ make mbx_config
$ make oldconfig
$ make dep
$ make pImage # with PPCBoot firmware
$ make zImage # with old bootstrap loader code

If this works, you can start modifying the configuration
using

$ make menuconfig

etc.

Hope this helps,

Wolfgang Denk
