u-boot/arch/powerpc/include/asm/iopin_8xx.h
Stefan Roese a47a12becf Move arch/ppc to arch/powerpc 
As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.

Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.
