Provide a helper function that board code can call to map TLBs when
setting up DDR.

All 86xx boards have been converted to the new code so we can
remove the old SPD DDR setup code.

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.

Resize the fdt to size + padding to 4k boundary

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
code when we fixup the initrd info in bootm on PPC.

Move the fdt resizing code out of ppc specific boot code and into

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
need the lmb to exist in a global state.
Moving it into the bootm_headers_t allows us to do that.

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.
