Rupjyoti Sarmah 8960f7ff50 powerpc/44x: PHY fixup for USB on canyonlands board
This fix is a reset for USB PHY that requires some amount of time for power
to be stable on Canyonlands.

Victor Gallardo d164f6d4f9 powerpc/4xx: Add suspend and idle support
Add suspend/resume support for 4xx compatible CPUs.
See /sys/power/state for available power states configured in.

Add two different idle states (idle-wait and idle-doze) controlled via sysfs.
Default is idle-wait.
	cat /sys/devices/system/cpu/cpu0/idle
	[wait] doze

To save additional power, use idle-doze.
	echo doze > /sys/devices/system/cpu/cpu0/idle
	cat /sys/devices/system/cpu/cpu0/idle
	wait [doze]

Torez Smith b4e8c8dd84 powerpc/4xx: Simple platform for the ISS 4xx simulator
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.

Josh Boyer 775d5a110b powerpc/44x: Add PowerPC 44x simple platform support
This adds a common board file for almost all of the "simple" PowerPC 44x
boards that exist today.  This is intended to be a single place to add
support for boards that do not differ in platform support from most of the
evaluation boards that are used as reference platforms.  Boards that have
specific requirements or custom hardware setup should still have their own
board.c file.

Jerone Young e92716f2aa [POWERPC] 4xx: Add idle wait support for 44x platforms
This changes the cpu_idle loop for 44x platforms to utilize the Wait Enable
feature of the CPU.  This helps virtulization solutions know when the guest
Linux kernel is in an idle state.

A command line option called "idle" is also added to allow people to change
the idle loop back to the original variation.  This is done by setting
"idle=spin" on the kernel command line.

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.

David Gibson 2cd9764770 [POWERPC] Add powerpc/platforms/44x, disable platforms/4xx for now
This prepares for Ebony/440 support by creating an
arch/powerpc/platforms/44x directory.  It is populated with a single
misc_44x.S file, into which is moved the 44x specific reset code from
head_44x.S (on the grounds that we should really stop clogging up the
head_* files with random asm helper routines).

At the same time, we disable the (empty save Kconfig and Makefile)
arch/powerpc/platforms/4xx directory from the arch/powerpc/platforms
Makefile.  Contrary to the comment in
arch/powerpc/platforms/4xx/Makefile, attempting to build such an empty
Makefile will fail, thus breaking compile for the 44x platforms we're
about to add.  It can go back in once we start porting some of the 40x
platforms (and thus it becomes non-empty).
