Geoff Levand 020533ef24 [POWERPC] cell: fix default zImage build target
Change CONFIG_PPC_CELL to CONFIG_PPC_IBM_CELL_BLADE in the powerpc boot
makefile.

CONFIG_PPC_CELL is used to build the generic cell processor support, and
is not an indication of platform.

Michael Ellerman dcf9065122 [POWERPC] Fix boot wrapper invocation if CROSS_COMPILE contains spaces
My CROSS_COMPILE is "ccache /opt/compilers/blah", which confuses
the boot wrapper script. Quote CROSS_COMPILE and CROSS32_COMPILE
so they can safely contain spaces.

Andrew Morton 5b9b5572c8 [PATCH] git-powerpc: wrapper: don't require execute permissions
If you lose the x bit (eg: by using patch(1)), powerpc won't build.  Be
defensive about it...

Paul Mackerras 2bf118197c [POWERPC] Create a "wrapper" script and use it in arch/powerpc/boot
This puts the knowledge of how to create various sorts of zImage
wrappers into a script called "wrapper" that could be used outside of
the kernel tree.  This changes arch/powerpc/boot so it first builds
the files that the wrapper script needs, then runs it to create
whatever flavours of zImage are required.

This version does uImages as well.  The zImage names are changed
slightly; zImage.pseries is the one with the PT_NOTE program header
entry added, and zImage.pmac is the one without.  If the
zImage.pseries gets made, it will also get hardlinked to zImage;
otherwise, if zImage.pmac is made, it gets hardlinked to zImage.

Mark A. Greer b2c5f61920 [POWERPC] Start arch/powerpc/boot code reorganization
This abstracts the operations used in the bootwrapper, and defines
the operations needed for the bootwrapper to run on an OF platform.

The operations have been divided up into platform ops (platform_ops),
firmware ops (fw_ops), device tree ops (dt_ops), and console ops
(console_ops).

The proper operations will be hooked up at runtime to provide the
functionality that you need.

Niels Kristian Bech Jensen fda7ffd25f [POWERPC] Add -fno-stack-protector to BOOTCFLAGS in arch/powerpc/boot/Makefile.
I got some undefined references to __stack_chk_fail in
arch/powerpc/boot/stdio.o and arch/powerpc/boot/prom.o when I was trying
to build a kernel on Ubuntu Edgy Eft - which includes Stack Smashing
Protection.

This patch adds -fno-stack-protector to BOOTCFLAGS in
arch/powerpc/boot/Makefile (why does BOOTCFLAGS depend on HOSTCFLAGS and
not CFLAGS?).

Regards,
Niels Kristian Bech Jensen

Richard Purdie 4f3865fb57 [PATCH] zlib_inflate: Upgrade library code to a recent version
Upgrade the zlib_inflate implementation in the kernel from a patched
version 1.1.3/4 to a patched 1.2.3.

The code in the kernel is about seven years old and I noticed that the
external zlib library's inflate performance was significantly faster (~50%)
than the code in the kernel on ARM (and faster again on x86_32).

For comparison the newer deflate code is 20% slower on ARM and 50% slower
on x86_32 but gives an approx 1% compression ratio improvement.  I don't
consider this to be an improvement for kernel use so have no plans to
change the zlib_deflate code.

Various changes have been made to the zlib code in the kernel, the most
significant being the extra functions/flush option used by ppp_deflate.
This update reimplements the features PPP needs to ensure it continues to
work.

This code has been tested on ARM under both JFFS2 (with zlib compression
enabled) and ppp_deflate and on x86_32.  JFFS2 sees an approx.  10% real
world file read speed improvement.

This patch also removes ZLIB_VERSION as it no longer has a correct value.
We don't need version checks anyway as the kernel's module handling will
take care of that for us.  This removal is also more in keeping with the
zlib author's wishes (http://www.zlib.net/zlib_faq.html#faq24) and I've
added something to the zlib.h header to note its a modified version.

so build them with ARCH=powerpc if we're 32-bit and powermac support

Paul Mackerras 66a45dd362 powerpc: Make COFF zImages for old 32-bit powermacs
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.

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).
