We don't actually need the kdb param as we are just using it to get
bd->bi_memsize which we can get from gd->bd->bi_memsize.  Also, if we
boot via OF we might not actually fill out a kdb.

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).

Do not pass image verification flag directly to related routines.
Simplify argument passing and move it to the bootm_header structure which
contains curently processed image specific data and is already being passed
on the argument list.

This patch adds framework for dual format images. Format detection is added
and the bootm controll flow is updated to include cases for new FIT format
uImages.

When the legacy (image_header based) format is detected appropriate
legacy specific handling is invoked. For the new (FIT based) format uImages
dual boot framework has a minial support, that will only print out a
corresponding debug messages. Implementation of the FIT specific handling will
be added in following patches.

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.

This routine assures that image (whether legacy or FIT) is not
in a special dataflash storage.

If image address is a dataflash address image is moved to system RAM.

This patch moves common pre-boot allocation steps shared between PPC
and M68K to a helper routines:

common:
- get_boot_sp_limit()
- get_boot_cmline()
- get_boot_kbd()

platform:
- set_clocks_in_mhz()

Ramdisk loading code, including initrd_high variable handling,
was duplicated for PPC and M68K platforms. This patch creates
common helper routine that is being called from both platform
do_bootm_linux() routines.
