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.
