Correct the loop for cacheflush. No idea where I copied the code from,
but the original does not work correct. Maybe the flush is not needed.

This patch removes all self references and fixes references to files
in the now defunct arch/ppc64 tree. I think this accomplises
everything wanted, though there might be a few references I missed.

Miboot images are apparently still used on some old 32-bit powermacs,
so build them with ARCH=powerpc if we're 32-bit and powermac support
is enabled.

The 601 processor will generate an alignment exception for accesses
which cross a page boundary. In the boot wrapper code, OF is still
handling all exceptions, and it doesn't have an alignment exception
handler that emulates the instruction and continues.
This changes the memcpy and memmove routines in the boot wrapper to
avoid doing unaligned accesses. If the source and destination are
misaligned with respect to each other, we just copy one byte at a
time.

This adds code to build zImage.coff and/or zImage.initrd.coff when
CONFIG_PPC32 and CONFIG_PPC_PMAC are defined. It also restructures
the OF client code and adds some workarounds for OF quirks on the
older machines.

Sam Ravnborg pointed out that calling if_changed was redundant in the
rule since a prerequisite had to have changed for us to get there.

powerpc: Add support for building uImages
Add support to build a kernel image bootable by u-boot.
Most of the makefile foo is taken from arch/ppc/boot/images/Makefile

Replacing the string labels with numbers saves 117 bytes in the final zImage.
These local labels are not discared.

This also extends the code to handle 32-bit ELF vmlinux files as well
as 64-bit ones. This is sufficient for booting on new-world 32-bit
powermacs (i.e. all recent machines).
