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.

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.

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.

As well as fdt_subnode_offset(), libfdt includes an
fdt_subnode_offset_namelen() function that takes the subnode name to
look up not as a NUL-terminated string, but as a string with an
explicit length. This can be useful when the caller has the name as
part of a longer string, such as a full path.
However, we don't have corresponding 'namelen' versions for
fdt_get_property() and fdt_getprop(). There are less obvious use
cases for these variants on property names, but there are
circumstances where they can be useful e.g. looking up property names
which need to be parsed from a longer string buffer such as user input
or a configuration file, or looking up an alias in a path with
IEEE1275 style aliases.
So, since it's very easy to implement such variants, this patch does
so. The original NUL-terminated variants are, of course, implemented
in terms of the namelen versions.

Enabling -Wcast-qual warnings in dtc shows up a number of places where
we are incorrectly discarding a const qualification. There are also
some places where we are intentionally discarding the 'const', and we
need an ugly cast through uintptr_t to suppress the warning. However,
most of these are pretty well isolated with the *_w() functions. So
in the interests of maximum safety with const qualifications, this
patch enables the warnings and fixes the existing complaints.

This patch turns on the -Wpointer-arith option in the dtc Makefile,
and fixes the resulting warnings due to using (void *) in pointer
arithmetic. While convenient, pointer arithmetic on void * is not
portable, so it's better that we avoid it, particularly in libfdt.
Also add necessary definition of uintptr_t needed by David Gibson's
changeset "dtc: Enable and fix -Wpointer-arith warnings" (the definition
comes from stdint.h, which u-boot doesn't have). -- gvb

This patch fixes some minor issues introduced with the patch:
ppc4xx: Optimize PLB4 Arbiter... from Prodyut Hazarika:
- Rework memory-queue and PLB arbiter optimization code, that the
local variable is not needed anymore. This removes one #ifdef.
- Use consistant spacing in ppc4xx.h header (XXX + 0x01 instead
of XXX+ 0x01). This was not introduced by Prodyut, just a
copy-paste problem.

PPC405EX and PPC460EX/GT/SX
- Read pipeline depth set to 4 for PPC440SP/SPE, PPC405EX, PPC460EX/GT/SX
processors
- Moved PLB4 Arbiter register definitions to ppc4xx.h since it is shared
across processors (405 and 440/460)
- Optimize Memory Queue settings for PPC440SP/SPE and PPC460EX/GT/SX
processors
- Add register bit definitions for Memory Queue Configuration registers

Move to using the environment variables 'ethaddr', 'eth1addr', etc..
instead of bd->bi_enetaddr, bi_enet1addr, etc.

ARM, i386, m68k and ppc all have identical implementations of strmhz().
Other architectures don't provide this function at all.
This patch moves strmhz() into lib_generic, reducing code duplication
and providing a more unified API across architectures.

This patch adds a hook whereby a board-specific routine can be called to
configure hardware for a PIO mode. The prototype for the board-specific
routine is:
int inline ide_set_piomode(int pio_mode)
ide_set_piomode should be prepared to configure hardware for a pio_mode
between 0 and 6, inclusive. It should return 0 on success or 1 on failure.
