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.
