mkuboot.sh provides a basic wrapper for the 'mkimage' utility. Using
mkuboot.sh provides clearer error reporting and allows a toolchain to
use its own 'mkimage' executable specified by ${CROSS_COMPILE}mkimage.
Additionally, this brings PowerPC in line with other architectures
which already call mkimage via mkuboot.sh.

Some XPedite52xx boards have a legacy boot loader requiring some special

MPC85xx platforms.

This adds the bootwrapper for the cuImage target and a compatible property
check for "pnpPNP,501" to the generic serial console support code.
The default link address for the cuImage target is set to 0x800000. This
allows to boot the kernel with AmigaOS4's second level bootloader, which
always loads a uImage at 0x500000.

Commit 9b09c6d909 ("powerpc: Change the
default link address for pSeries zImage kernels") changed the
real-base value in the CHRP note added by addnote to the zImage from
12MB to 32MB. It turns out that this causes unnecessary extra reboots
on old 32-bit CHRP machines. This therefore adds a -r flag to addnote
to allow us to specify what real-base value it should put in the CHRP
note, and adjusts the wrapper script to pass -r c00000 to addnote when
making a zImage for a CHRP machine. Also, CHRP machines ignore the
RPA note, so we don't need to arrange for it to be the same as the
kernel's.

Commit 9b09c6d909 ("powerpc: Change the
default link address for pSeries zImage kernels") changed the
real-base value in the CHRP note added by the addnote program from
12MB to 32MB to give more space for Open Firmware to load the zImage.
(The real-base value says where we want OF to position itself in
memory.) However, this change was ineffective on most pSeries
machines, because the RPA note added by addnote has the "ignore me"
flag set to 1. This was intended to tell OF to ignore just the RPA
note, but has the side effect of also making OF ignore the CHRP note
(at least on most pSeries machines).
To solve this we have to set the "ignore me" flag to 0 in the RPA
note. (We can't just omit the RPA note because that is equivalent to
having an RPA note with default values, and the default values are not
what we want.) However, then we have to make sure the values in the
zImage's RPA note match up with the values that the kernel supplies
later in prom_init.c with either the ibm,client-architecture-support
call or the process-elf-header call in prom_send_capabilities().
So this sets the "ignore me" flag in the RPA note in addnote to 0, and
adjusts the RPA note values in addnote.c and in prom_init.c to be
consistent with each other and with the values in ibm_architecture_vec.
However, since the wrapper is independent of the kernel, this doesn't
ensure that the notes will stay consistent. To ensure that, this adds
code to addnote.c so that it can extract the kernel's RPA note from
the kernel binary and put that in the zImage. To that end, we put the
kernel's fake ELF header (which contains the kernel's RPA note) into
its own section, and arrange for wrapper to pull out that section with
objcopy and pass it to addnote, which then extracts the RPA note from
it and transfers it to the zImage.

Currently we set the start of the .text section to be 4Mb for pSeries.
In situations where the zImage is > 8Mb we'll fail to boot (due to
overlapping with OF). Move .text in a zImage from 4MB to 64MB
(well past OF).
We still will not be able to load large zImage unless we also move OF,
to that end, add a note to the zImage ELF to move OF to 32Mb. If this
is the very first kernel booted then we'll need to move OF manually by
setting real-base.

Now that we properly set the physical address in the program header of the
vmlinux ELF we can extract it to properly set the load and entry point for
u-boot uImages. Before we always hard coded the load & entry point to 0.
However there are situations that the kernel may be built with a non-zero
physical address.
We use objdump to extract the PHDR. We assume that there is only one
PHDR in the vmlinux of type LOAD.

o Use the dot symbol to set the size of __system_reset_overlay. The
assembler will then emit an error if the overlay code is too big.
o Remove some unused instructions.

o Add a check for null pointer writes.

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.
