This patch forward declares struct device_node to fix a compile error
when of_fdt.h is included, but of.h is not.  Alternately, including
linux/of.h could have been added to of_fdt.h, but that pulls in a lot
of unnecessary declarations when only working with the flattened
form.

When we switched sparc from using 'int's to 'phandle's (which is a u32), we

explicitly cast the phandles to s32.

Pull in recent changes from the main dtc repository. These changes
primarily allow multiple device trees to be declared which are merged
by dtc. This feature allows us to include a basic dts file and then
provide more information for the specific system through the merging
functionality.

unflatten_device_tree has two dependencies on things that happen
during boot time.  Firstly, it references the initial device tree
directly. Secondly, it allocates memory using the early boot
allocator.  This patch factors out these dependencies and uses
the new __unflatten_device_tree function to implement a driver-visible
fdt_unflatten_tree function, which can be used to unflatten a
blob after boot time.

V2:
- remove extra __va() call
- make dt_alloc functions return void *.  This doesn't fix the general
  strangeness in this code that constantly casts back and forth between
  unsigned long and __be32 *

unflatten_dt_node is a helper function that does most of the work to

The device tree code is now in two pieces: some which can be used generically
on any platform which selects CONFIG_OF_FLATTREE, and some early which is used
at boot time on only a few architectures.  This patch segregates the early
code so that only those architectures which care about it need compile it.
This also means that some of the requirements in the early code (such as
a cmd_line variable) that most architectures (e.g. X86) don't provide
can be ignored.

This patch changes u32 to __be32 for all "ranges", "prop" and "addr" and
such. Those variables are pointing to the device tree which contains
integers in big endian format.

Most functions are doing it right because of_read_number() is doing the
right thing for them. of_bus_isa_get_flags(), of_bus_pci_get_flags() and
of_bus_isa_map() were accessing the data directly and were doing it wrong.

This patch adds support for linking device tree blob(s) into
vmlinux. Modifies asm-generic/vmlinux.lds.h to add linking
.dtb sections into vmlinux. To maintain compatiblity with the of/fdt
driver code platforms MUST copy the blob to a non-init memory location
before the kernel frees the .init.* sections in the image.

Modifies scripts/Makefile.lib to add a kbuild command to
compile DTS files to device tree blobs and a rule to create objects to
wrap the blobs for linking.

STRUCT_ALIGNMENT is defined in vmlinux.lds.h for use in the rule to
create wrapper objects for the dtb in Makefile.lib.  The
STRUCT_ALIGN() macro in vmlinux.lds.h is modified to use the
STRUCT_ALIGNMENT definition.

The DTB's are placed on 32 byte boundries to allow parsing the blob
with driver/of/fdt.c during early boot without having to copy the blob
to get the structure alignment GCC expects.

A DTB is linked in by adding the DTB object to the list of objects to
be linked into vmlinux in the archtecture specific Makefile using
   obj-y += foo.dtb.o
