The main purpose of this rewrite it to be able to share the same
initialization code on all FSL PowerPC products that have DDR
controllers.  (83xx, 85xx, 86xx).

The code is broken up into the following steps:
	GET_SPD
	COMPUTE_DIMM_PARMS
	COMPUTE_COMMON_PARMS
	GATHER_OPTS
	ASSIGN_ADDRESSES
	COMPUTE_REGS
	PROGRAM_REGS

This allows us to share more code an easily allow for board specific code
overrides.

Additionally this code base adds support for >4G of DDR and provides a
foundation for supporting interleaving on processors with more than one
controller.

There is no need for each OS specific function to call do_reset() we
can just do it once in bootm. This means its feasible on an error for
the OS boot function to return.

Also, remove passing in cmd_tbl_t as its not needed by the OS boot
functions.  flag isn't currently used but might be in the future so
we left it alone.

Created a new fdt_initrd() to deal with setting the initrd properties
in the device tree and fixing up the mem reserve.  We can use this
both in the choosen node handling and lets us remove some duplicated

Created a bootm_start() that handles the parsing and detection of all
the images that will be used by the bootm command (OS, ramdisk, fdt).
As part of this we now tract all the relevant image offsets in the
bootm_headers_t struct. This will allow us to have all the needed
state for future sub-commands and lets us reduce a bit of arch
specific code on SPARC.

Created a bootm_load_os() that deals with decompression and loading
the OS image.

To allow for persistent state between future bootm subcommands we

PCI I/O space is currently mapped 1:1 at 0xFA000000. Linux requires
PCI I/O space to start at 0 on the PCI bus. This patch maps PCI I/O
space such that 0xFA000000 in the processor's address space maps to 0
on the PCI I/O bus.
