Introduce basic support for the Freescale P1022DS reference board, based on the
Freescale BSP for this board.  This patch excludes the DIU, SSI, and MMC/SD
drivers.  Only a 36-bit DTS is provided.

Update mpc86xx_smp_defconfig and mpc85xx_defconfig to support the P1022DS.
This means enabling 64-bit physical address support, increasing the maximum
zone order to 12 (to allow the DIU driver to allocate large chunks), and
clean up the audio options to disable the deprecated OSS support.

P1021 processors have no dedicated ROM to store the QE microcode,
so the fimrware is stored externally, and it is U-Boot responsibility
to load it. It might be that the board is booting without QE, e.g.
currently U-Boot doesn't support QE for P1021MDS boards, which means
that QE isn't initialized, and so the board hangs early at boot.

This patch fixes the issue by marking QE as disabled and checking the
state in the probing code. U-Boot should fixup the state if it
initialized the QE.

Since USB2 is shared with local bus, either local bus or USB2

This patch adds NOR FLASH MTD support to the Katmai (440SPe) dts file.
For this the OPB ranges address is mapped differently (base 0x00000000
-> 0xe0000000). This results in the address being identical to the lower
32bit of its physical address. This is needed for the MTD mapping to work
correctly, since U-Boot will insert the physical addresses of the EBC
chip selects into the EBC ranges property. This is the way its done in
most other 4xx dts files as well.

Additionally with a small whitespace cleanup.

Commit ac4c2a3b 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).

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.
