I started from scratch and am trying to build the cuImage. I get this
compiler error.
arch/powerpc/boot/cuboot-pq2.c:14:20: error: bitops.h: No such file or directory
arch/powerpc/boot/cuboot-pq2.c: In function 'fixup_pci':
arch/powerpc/boot/cuboot-pq2.c:205: warning: implicit declaration of
function '__ilog2_u32'
I looks as though cuboot-pq2.c expects bitops.h to be in the same
directory, but it has moved to
linux/include/asm-powerpc/bitops.h
Did you run into this problem?
