powerpc/boot: Add an ePAPR compliant boot wrapper

2011-04-20T06:59:21+00:00

This is a first cut at making bootwrapper code which will
produce a zImage compliant with the requirements set down
by ePAPR.

This is a very simple bootwrapper, taking the device tree
blob supplied by the ePAPR boot program and passing it on
to the kernel. It builds on the earlier patch to build a
relocatable ET_DYN zImage to meet the other ePAPR image
requirements.

For good measure we have some paranoid checks which will
generate warnings if some of the ePAPR entry condition
guarantees are not met.

powerpc/boot/dts: Install dts from the right directory

2011-01-21T03:08:38+00:00

The dts-installed variable is initialised using a wildcard path that
will be expanded relative to the build directory.  Use the existing
variable dtstree to generate an absolute wildcard path that will work
when building in a separate directory.

powerpc/boot: Remove addRamdisk.c since it is now unused

2010-06-15T05:02:32+00:00

It was used in the dim distant past for adding initrds to images
for legacy iSeries, but it's not even used for that now that we
have initramfs.  So remove it.

powerpc/4xx: Simple platform for the ISS 4xx simulator

2010-05-05T15:11:56+00:00

This is a trivial 4xx plaform that uses the new simple bsp from
Josh and is handy to use in simulators such as ISS or even Mambo
who don't properly implement most of the actual devices in the
SoC but really only the core.

powerpc: Add a new zImage for maple using a different link address

2010-04-07T04:12:36+00:00

The maple platform failed to load because it's firmware could not take a
link address of 0x4000000.  A new platform type with a link address of
0x400000 had to be created for the maple.

zlib: Fix build of powerpc boot wrapper

2010-01-14T00:13:39+00:00

Commit ac4c2a3bbe5db5fc570b1d0ee1e474db7cb22585 broke the build
of all powerpc boot wrappers.

It attempts to add an include of autoconf.h but used the wrong
path for it. It also adds -D__KERNEL__ to our boot wrapper, both
things that we pretty much didn't do on purpose so far.

We want our boot wrapper to remain independent enough of the kernel
for various reasons, one of them being that you can "wrap" an existing
kernel at distro install time which allows to ship one kernel image
and a set of boot wrappers for different platforms, the wrappers
don't have to be built out of the same kernel build tree.

It's also incorrect to do what the patch does in our boot environment
since we may not have a proper alignment exception handler which means
we may not be able to fixup the few cases where an unaligned access will
need SW emulation (depends on the core variant, could be when crossing
page or segment boundaries for example).

This patch fixes it by putting the old code back in and using the
new "fancy" variant only when CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS
is set, which happens not to be set on powerpc since we don't include
autoconf.h. It also reverts the changes to our boot wrapper Makefile.

This means that x86 should, afaik, keep the optimisations since its
boot wrapper does include autoconf.h and define __KERNEL__ (though I
doubt they make that much different outside of slow embedded processors).

zlib: optimize inffast when copying direct from output

2010-01-11T17:34:04+00:00

JFFS2 uses lesser compression ratio and inflate always ends up in "copy
direct from output" case.

This patch tries to optimize the direct copy procedure.  Uses
get_unaligned() but only in one place.

The copy loop just above this one can also use this optimization, but I
havn't done so as I have not tested if it is a win there too.

On my MPC8321 this is about 17% faster on my JFFS2 root FS than the
original.

powerpc: wii: bootwrapper bits

2009-12-13T05:24:29+00:00

Add support for the Nintendo Wii video game console to the powerpc
bootwrapper.

dtbImage.wii is a wrapped image that contains a flat device tree,
an entry point compatible with the Homebrew Channel and BootMii,
and an optional initrd.
