[PATCH] [RFC] powerpc: Xilinx: adding virtex5 powerpc 440 support

This is an early patch against the mainline that I wanted to start
getting comments on.
I would appreciate any feedback.
I already see a few things that I need to look into myself.
1. I'm not sure why we need to disable the interrupts in the
bootstrap loader?
2. I see some SecetLab copyright in new files that might be just a
cut/paste type error.
3. I don't see the cputable.c up to date with the Xilinx specific
440.
Thanks,
John Linn

Subject: [PATCH] powerpc: Xilinx: adding virtex5 powerpc 440 support
The following files add support for Virtex5 with Powerpc 440.
Device trees are currently handled differently than other embedded
systems as there may not be a boot loader such that the device
tree is compiled into the kernel or pulled from a BRAM.
The UART 16550 has extra initialization in the bootstrap loader
since a boot loader is not used many times.

+config BUILD_RAW_IMAGE
+ bool "Build firmware-independent image"
+ select WANT_DEVICE_TREE
+ help
+ If this is enabled, a firmware independent "raw" image will be
+ built, as zImage.raw. This requires a completely filled-in
+ device tree, with the following labels:
+
+ mem_size_cells: on /#address-cells
+ memsize: on the size portion of /memory/reg
+ timebase: on the boot CPU's timebase property
+
+config DEVICE_TREE
+ string "Static device tree source file"
+ depends on WANT_DEVICE_TREE
+ help
+ This specifies the device tree source (.dts) file to be
+ compiled and included when building the bootwrapper. If a
+ relative filename is given, then it will be relative to
+ arch/powerpc/boot/dts. If you are not using the bootwrapper,
+ or do not need to build a dts into the bootwrapper, this
+ field is ignored.
+
+ For example, this is required when building a cuImage target
+ for an older U-Boot, which cannot pass a device tree itself.
+ Such a kernel will not work with a newer U-Boot that tries to
+ pass a device tree (unless you tell it not to). If your
U-Boot
+ does not mention a device tree in "help bootm", then use the
+ cuImage target and specify a device tree here. Otherwise, use
+ the uImage target and leave this field blank.
+
+config COMPRESSED_DEVICE_TREE
+ bool "Use compressed device tree"
+ depends on XILINX_VIRTEX
+ depends on WANT_DEVICE_TREE
+ help
+ In Xilinx FPGAs, the hardware can change quite dramatically
while
+ still running the same kernel. In this case and other similar
+ ones, it is preferable to associate the device tree with a
+ particular build of the hardware design. This configuration
+ option assumes that the device tree blob has been compressed
and
+ stored in Block RAM in the FPGA design. Typically, such a
block
+ ram is available in order to provide a bootloop or other code
+ close to the reset vector at the top of the address space. By
+ default, the parameter options associated with this
configuration
+ assumes that exactly one block ram (2KB) of storage is
available,
+ which should be sufficient for most designs. If necessary in
a
+ particular design, due to boot code requirement or a large
number
+ of devices, this address (and the corresponding parameters in
the
+ EDK design) must be modified.
+
+ Note that in some highly area constrained designs, no block
rams
+ may be available in the design, and some other mechanism may
be
+ used to hold the processor in reset while external memory is
+ initialized with processor code. In such cases, that
mechanism
+ should also be used to load the device tree at an appropriate
+ location, and the parameters associated with this
configuration
+ option should be modified to point to that location in
external
+ memory.
