681c774d0f [PATCH] ppc64 boot: remove sysmap from required filenames
A stripped vmlinux does not contain enough symbols to recreate the
System.map.  The System.map file is only used to determine the end of
the runtime memory size.  This is the same value (rounded up to
PAGE_SIZE) as ->memsiz in the ELF program header.

Also, the target vmlinux.initrd doesnt work in 2.6.14:

  arch/ppc64/boot/addRamDisk arch/ppc64/boot/ramdisk.image.gz vmlinux.strip arch/ppc64/boot/vmlinux.initrd
  Name of vmlinux output file missing.

c8e3c8b21b [PATCH] ppc64: Fix zImage boot
The zImage wrapper has a bug where it doesn't claim() the memory for the
kernel properly, it forgets to take into account the offset between the ELF
header and the kernel itself.  This results on some machines, like G5s,
into a kernel that crashes at boot when clearing the BSS.

18c5332bc1 [PATCH] ppc64: change name of target file during make install
'make install' creates a /boot/zImage[.vmode] file when the defconfig is used.

It uses the second arg as file content, which is the vmlinux, and the 5th
arg as file name, which is the BOOTIMAGE name.

A comment in an earlier patch to install.sh states that yaboot can not load
a zImage+initrd combo.  This was true in kernel 2.6.5 because it did use
bi_recs to pass the initrd info.  But this concept was always broken.
Register r3 holds the initrd address and r4 holds the initrd size.  This
works with all kernel versions.  The current code in main.c leaves r3 and
r4 alone, so the kernel should be able to see and use the memory range with
the initrd content.

If one wants to rerun mkinitrd, it is currently hard to get the uname -r
value for the installed zImage.  Without this info, mkinitrd can not know
what modules to use.  This would be fixable by including the /proc/version
output of the new kernel.  But it is simpler to just use the plain vmlinux.

So all this patch does is to write to /boot/vmlinux instead to /boot/zImage

8a76baf020 [PATCH] ppc64 boot: remove need for imagesize.c
Compute the vmlinux size at runtime.

Use Z_FULL_FLUSH instead of Z_FINISH, to extract only the ELF header
and ELF program header.

 ->p_memsz is the required memory range for the executable, including bss
 ->p_filesz is the size of .text, .data and other runtime sections

These values must be used for the claim call.
All additional memory needed by the kernel is claimed in prom_init, remove
the extra Mb.

Pass the full memsize as target area to gunzip, otherwise not everything
will be uncompressed.

flush_cache has to flush all runtime sections, do not reduce the memrange
by the ->p_offset value because its just that: an offset.

Remove the Makefile code to produce an imagesize.c, its not needed anymore.
Remove all FORCE flags, to not rebuild the zImage if vmlinux was not changed.

3cc747e964 [PATCH] PPC64: large INITRD causes kernel not to boot
In PPC64 there are number of problems in arch/ppc64/boot/main.c that
prevent a kernel from making use of a large (greater than ~16MB) INITRD.
This is 64 bit architecture and really large INITRD images should be
possible.

Simply put the existing code has a fixed reservation (claim) address and
once the kernel plus initrd image are large enough to pass this address
all sorts of bad things occur. The fix is the dynamically establish the
first claim address above the loaded kernel plus initrd (plus some
"padding" and rounding). If PROG_START is defined this will be used as
the minimum safe address - currently known to be 0x01400000 for the
firmwares tested so far.

0f8e2d62fa [PATCH] use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh
The attached patch causes the various arch specific install.sh scripts to
look for ${CROSS_COMPILE}installkernel rather than just installkernel (in
both /sbin/ and ~/bin/ where the script already did this).  This allows you
to have e.g.  arm-linux-installkernel as a handy way to install on your
cross target.  It also prevents the script picking up on the host
/sbin/installkernel which causes the script to fall through and do the
install itself (which is what I actually use myself, with $INSTALL_PATH
set).

I don't believe it causes back-compatibility problems since calling the
host installkernel was never likely to work or be what you wanted when
cross compiling anyway.  If $CROSS_COMPILE isn't set then nothing changes.

I only use ARM and i386 myself but I figured it couldn't hurt to do the
whole lot.  I've cc'd those who I hope are the arch maintainers for files
that I've touched.
