a166fbca20 powerpc: fix 8xx and 82xx type-punning warnings with GCC 4.7
C99's strict aliasing rules are insane to use in low-level code such as a
bootloader, but as Wolfgang has rejected -fno-strict-aliasing in the
past, add a union so that 16-bit accesses can be performed.

Compile-tested only.

e4a95d112e powerpc: Consolidate bootcount_{store|load} for PowerPC
This patch consolidates bootcount_{store|load} for PowerPC by
implementing a common version in arch/powerpc/lib/bootcount.c. This
code is now used by all PowerPC variants that currently have these
functions implemented.

The functions now use the proper IO-accessor functions to read/write the
values.

This code also supports two different bootcount versions:

a) Use 2 separate words (2 * 32bit) to store the bootcounter
b) Use only 1 word (2 * 16bit) to store the bootcounter

Version b) was already used by MPC5xxx.

a47a12becf Move arch/ppc to arch/powerpc
As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.

Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.
