a4f740cf33 of/flattree: Add of_flat_dt_match() helper function
This patch adds of_flat_dt_match() which tests a node for
compatibility with a list of values and converts the relevant powerpc
platform code to use it.  This approach simplifies the board support
code a bit.

c76986cca8 Remove REDWOOD_[456] config options and conditional code
The config options for REDWOOD_[456] were commented out in the powerpc
Kconfig. The ifdefs referencing this options therefore are dead and all
references to this can be removed (Also dependencies in other KConfig

0cdf50a7c6 powerpc/40x: Add support for the ESTeem 195E (PPC405EP) SBC
This patch adds support for the ESTeem 195E Hotfoot SBC.

There are several variants of the SBC deployed, single/dual
ethernet+serial, and also 4MB/8MB flash variations.  In the interest of
having a single kernel image boot on all boards, the cuboot shim detects
the differences and mangles the DTS tree appropriately.

With the exception of the CF interface that was never populated on
production boards, this code/DTS supports all boardpop options.

7fe519c207 powerpc: Introduce ppc_pci_flags accessors
Currently there are a number of platforms that open code access to
the ppc_pci_flags global variable.  However, that variable is not
present if CONFIG_PCI is not set, which can lead to a build break.

This introduces a number of accessor functions that are defined
to be empty in the case of CONFIG_PCI being disabled.  The
various platform files in the kernel are updated to use these.

8105fa8859 powerpc/40x: Add PowerPC 40x simple platform support
This adds a common board file for almost all of the "simple" PowerPC 40x
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.

The first board ported to this is the AMCC PowerPC 405EZ Acadia board.

93173ce272 [POWERPC] 4xx: Create common ppc4xx_reset_system() in ppc4xx_soc.c
This patch creates a common system reset routine for all 40x and 44x
systems. Previously only a 44x routine existed. But since this system
reset via the debug control register is common for 40x and 44x let's
share this code for all those platforms in ppc4xx_soc.c.

This patch also enables CONFIG_4xx_SOC for all 40x and 44x platforms.

Tested on Kilauea (405EX) and Canyonlands (440EX).

22258fa40e [POWERPC] Enable RTC for Ebony and Walnut (v2)
This patch extends the Ebony and Walnut platform code to instantiate
the existing ds1742 RTC class driver for the DS1743 RTC/NVRAM chip
found on both those boards.  The patch uses a helper function to scan
the device tree and instantiate the appropriate platform_device based
on it, so it should be easy to extend for other boards which have mmio
mapped RTC chips.

Along with this, the device tree binding for the ds1743 chips is
tweaked, based on the existing DS1385 OF binding found at:
	http://playground.sun.com/1275/proposals/Closed/Remanded/Accepted/346-it.txt
Although that document covers the NVRAM portion of the chip, whereas
here we're interested in the RTC portion, so it's not entirely clear
if that's a good model.

This implements only RTC class driver support - that is /dev/rtc0, not
/dev/rtc, and the low-level get/set time callbacks remain
unimplemented.  That means in order to get at the clock you will
either need a modified version of hwclock which will look at
/dev/rtc0, or you'll need to configure udev to symlink rtc0 to rtc.

25c24f3dc7 [POWERPC] pci32: 4xx embedded platforms want to reassign all PCI resources
This makes 4xx embedded platforms re-assign all PCI resources as we
pretty much never care about what the various firmwares have done on
these, it's generally not compatible with the way the kernel will map
the bridges.

We still need to also enable bus renumbering on some of them, but I
will do that from a separate patch after I've fixed 4xx PCIe to handle
all bus numbers.

619740384c [POWERPC] 4xx: EP405 boards support for arch/powerpc
Brings EP405 support to arch/powerpc. The IRQ routing for the CPLD
comes from a device-tree property, PCI is working to the point where
I can see the video card, USB device, and south bridge.

This should work with both EP405 and EP405PC.

I've not totally figured out how IRQs are wired on this hardware
though, thus at this stage, expect only USB interrupts working,
pretty much the same as what arch/ppc did.

Also, the flash, nvram, rtc and temp control still have to be wired.
