143580ecfb [POWERPC] Fix bootwrapper builds with newer gcc versions
GCC 4.4.x looks to be adding support for generating out-of-line register
saves/restores based on:

http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html

This breaks the bootwrapper as we'd need to link with libgcc to get the
implementation of the register save/restores.

To workaround this issue, we just stole the save/restore code from gcc
and simplified it down for our needs (integer only).

595be948cc [POWERPC] Fix zImage-dtb.initrd build error
The pattern substitution rules were failing when used with zImage-dtb
targets.  If zImage-dtb.initrd was selected, the pattern substitution
would generate "zImage.initrd-dtb" instead of "zImage-dtb.initrd" which
caused the build to fail.

This renames zImage-dtb to dtbImage to avoid the problem entirely.
By not using the zImage prefix then is no potential for namespace
collisions.

2543133381 [POWERPC] bootwrapper: Build multiple cuImages
Currently, the kernel uses CONFIG_DEVICE_TREE to wrap a kernel image
with a fdt blob which means for any given configuration only one dts
file can be selected and so support for only one board can be built

This moves the selection of the default .dts file out of the kernel
config and into the bootwrapper makefile.  The makefile chooses which
images to build based on the kernel config and the dts source file
name is taken directly from the image name.  For example "cuImage.ebony"
will use "ebony.dts" as the device tree source file.

In addition, this patch allows a specific image to be requested from the
command line by adding "cuImage.%" and "treeImage.%" targets to the list
of valid built targets in arch/powerpc/Makefile.  This allows the default
dts selection to be overridden.

Another advantage to this change is it allows a single defconfig to be
supplied for all boards using the same chip family and only differing in
the device tree.

Important note: This patch adds two new zImage targets; zImage.dtb.% and
zImage.dtb.initrd.% for zImages with embedded dtb files.  Currently
there are 5 platforms which require this: ps3, ep405, mpc885ads, ep88xc,
adder875-redboot and ep8248e.  This patch *changes the zImage filenames*
for those platforms.  ie. 'zImage.ps3' is now 'zImage.dtb.ps3'.

This new zImage.dtb targets were added so that the .dts file could be
part of the dependancies list for building them.

Brings EP405 support to arch/powerpc. The IRQ routing for the CPLD
comes from a device-tree property, PCI is working to the point where

This should work with both EP405 and EP405PC.

I've not totally figured out how IRQs are wired on this hardware
though, thus at this stage, expect only USB interrupts working,
pretty much the same as what arch/ppc did.

Also, the flash, nvram, rtc and temp control still have to be wired.

The mpc8xx/pq2 set_clocks() functions modify common properties in

bafdb64577 [POWERPC] PS3: Bootwrapper support.
Add support to build the PS3 flash rom image and remove some unneeded
lmb calls.

The PS3's lv1 loader supports loading gzipped binary images from flash
rom to addr zero. The loader enters the image at addr 0x100.

In this implementation a bootwrapper overlay is use to arrange for the
kernel to be loaded to addr zero and to have a suitable bootwrapper
entry at 0x100.  To construct the rom image, 0x100 bytes from offset
0x100 in the kernel is copied to the bootwrapper symbol
__system_reset_kernel.  The 0x100 bytes at the bootwrapper symbol
__system_reset_overlay is then copied to offset 0x100.  At runtime the
bootwrapper program copies the 0x100 bytes at __system_reset_kernel to
addr 0x100.

zImage.ps3 is a wrapped image that contains a flat device tree, an lv1
compatible entry point, and an optional initrd.  otheros.bld is the gzip
compresed rom image built from zImage.ps3.  otheros.bld is suitable for
programming into the PS3 boot flash memory.
