Add the ability to break the steps of the bootm command into several
subcommands: start, loados, ramdisk, fdt, bdt, cmdline, prep, go.
This allows us to do things like manipulate device trees before
they are passed to a booting kernel or setup memory for a secondary
core in multicore situations.
Not all OS types support all subcommands (currently only start, loados,
ramdisk, fdt, and go are supported).

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.

This reverts commit f5614e7926.
The commit was based on a misunderstanding of the (documented)
meaning of the 'autostart' environment variable. It might cause
boards to hang if 'autostart' was used, with the potential to brick
them. Go back to the documented behaviour.

Before new uImage code was merged, bootm code allowed for the kernel image to
get overwritten during decompresion. new uImage introduced a check for image
overwrites and refused to boot the image that got overwritten. This patch
restores the old behavior. It also adds a warning when the image overwriten is
a multi-image file, because in such case accessing componentes other than the
first one will fail.

Support for the new uImage format (FIT) is added to mkimage tool.
Commandline syntax is appropriately extended:

mkimage (together with dtc) takes fit-image.its and referenced therein
binaries (like vmlinux.bin.gz) as inputs, and produces fit-image file -- the
final image that can be transferred to the target (e.g., via tftp) and then
booted using the bootm command in U-Boot.

Convert generic ramdisk_high(), get_boot_cmdline(), get_boot_kbd()
functions over to using lmb for allocation of the ramdisk, command line
and kernel bd info.
Convert PPC specific fdt_relocate() to use lmb for allocation of the device
tree.
Provided a weak function that board code can call to do additional
lmb reserves if needed.
Also introduce the concept of bootmap_base to specify the offset in
physical memory that the bootmap is located at. This is used for
allocations of the cmdline, kernel bd, and device tree as they should
be contained within bootmap_base and bootmap_base + CFG_BOOTMAPSZ.

Dual format image code must properly handle all three FDT passing methods:
- raw FDT blob passed
- FDT blob embedded in the legacy uImage
- FDT blob embedded in the new uImage
This patch enables proper raw FDT handling when no FIT imaeg support
is compiled in. This is a bit tricky as we must dected FIT format even
when FIT uImage handling is not enabled as both FIT uImages and raw FDT
blobs use tha same low level format (libfdt).

Introducing routines for parsing new uImage format bootm arguments:
[<addr>]#<conf> - configuration specification
[<addr>]:<subimg> - subimage specification
New format images can contain multiple subimages of the same type. For example
a single new format image file can contain three kernels, two ramdisks and a
couple of FDT blobs. Subimage and configuration specifications are extensions
to bootm (and other image-related commands) arguments' syntax that allow to
specify which particular subimage should be operated on.
Subimage specification is used to denote a particular subimage. Configurations
are a bit more complex -- they are used to define a particualr booting setup,
for example a (kernel, fdt blob) pair, or a (kernel, ramdisk, fdt blob) tuple,
etc.
