[PATCH] powerpc: correct cacheflush loop in zImage

2006-03-16T05:54:57+00:00

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.

powerpc/32: Generate miboot images with ARCH=powerpc

2006-01-15T02:00:08+00:00

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.

powerpc: Avoid unaligned loads and stores in boot memcpy code

2006-01-14T04:06:51+00:00

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.

powerpc: Make COFF zImages for old 32-bit powermacs

2006-01-14T04:04:06+00:00

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.

2006-01-11T05:28:13+00:00

clean-files was being set twice rather than being appended to.

[PATCH] powerpc: Fix suboptimal uImage target

2006-01-09T03:50:25+00:00

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

[PATCH] ppc boot: replace string labels with numbers

2005-11-18T02:18:16+00:00

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

powerpc: Move ppc64 boot wrapper code over to arch/powerpc

2005-11-16T02:52:21+00:00

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).
