dbdf04c401 [CELL] driver for DDR2 memory on AXON
The Axon bridge chip used on new Cell/B.E. based blade servers
comes with a DDR2 memory controller that can be used to
attach cheap memory modules, as opposed to the high-speed
XDR memory that is used by the CPU itself.

Since the memory controller does not participate in the
cache coherency protocol, we can not use the memory direcly
for Linux applications, but by providing a block device
it can be used for swap space, temporary file storage and
through the use of the direct_access block device operation
for mapping into user addresses, when it is mounted with
an appropriate file system.

bf7c036fb4 [POWERPC] Remove PCI-e errata for MPC8641 silicon ver 1.0
Remove errata for PCI-e support of Rev 1.0 of MPC8641 since its considered
obselete and is not production level silicon from Freescale.

b9fd305db0 [POWERPC] move 82xx/83xx/86xx Kconfig options to platform selection
The cores used in the MPC82xx/83xx/86xx embedded controllers are very similar
to those in the 32 bit general-purpose processors, so it makes sense to
treat them as the same CPU family.

Choosing between the embedded platforms and the multiplatform code is
now done in the platform menu, but functionally everything stays the
same.

f21f49ea63 [POWERPC] Remove the dregs of APUS support from arch/powerpc
APUS (the Amiga Power-Up System) is not supported under arch/powerpc
and it's unlikely it ever will be.  Therefore, this patch removes the
fragments of APUS support code from arch/powerpc which have been
copied from arch/ppc.

A few APUS references are left in asm-powerpc in .h files which are
still used from arch/ppc.

f6dfc80554 [POWERPC] Support for the Ebony 440GP reference board in arch/powerpc
This adds platform support code for the Ebony (440GP) evaluation
board.  This includes both code in arch/powerpc/platforms/44x for
board initialization, and zImage wrapper code to correctly tweak the
flattened device tree based on information from the firmware.  The
zImage supports both IBM OpenBIOS (aka "treeboot") and old versions of
uboot which don't support a flattened device tree.

c146c958dc [POWERPC] Clean up cpufreq Kconfig dependencies
Shuffle Kconfig order, making the platform drivers menu depend on the global
option instead of each driver being dependent on it.

Also fix dependency of PPC_PMAC on the G5 one.

7d776cb596 [POWERPC] QE: automatically select QE options
Change the Kconfig files so that the Freescale QE options are automatically
selected if a QE device is selected.  Previously, you'd need to manually
select UCC_FAST if you want any "fast" UCC devices, such as Gigabit Ethernet.
Now, the QE Gigabit Ethernet option is always available if the device has a
QE, and UCC_FAST is automatically enabled.  A side-effect is that the
"QE Options" menu no longer exists.
