Am I missing something from the build in order for the final link to
complete correctly?
Hm, repository looks okay, and I didn't run into this yet. Possibly you
are using different binutils?
Presumably you did try make clean CROSS_COMPILE=... :)
I chose not to apply one hunk from Rene Rebe since not needed here.
Maybe the above .rodata.str1.4 would end up in .rodata this way?
Make it link at al.

Hi Andreas,
That patch definitely helps as it reduces the error to just:
powerpc-elf-ld: .objs/main.out section .text.startup will not fit in
region start
powerpc-elf-ld: section .text [0000000005800400 -> 0000000005812e23]
overlaps section .text.startup [0000000005800054 -> 00000000058006d7]
powerpc-elf-ld: region start overflowed by 728 bytes
So if I then apply the same trick to the .text section (patch attached)
then I get a successful link and an output image. The output image does
execute under QEMU, although for all of the CD images I have it reports
"ERROR: Found no boot partition!". Do you have pointers to any ISOs that
can boot from the resulting image?
FWIW my cross-compile setup is based upon binutils 2.19.
ATB,
Mark.
