This patch introduces the following prefix convention for the
image format handling and bootm related code:
genimg_ - dual format shared code
image_ - legacy uImage format specific code
fit_ - new uImage format specific code
boot_ - booting process related code
Related routines are renamed and a few pieces of code are moved around and
re-grouped.

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.

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.

Commit 073e1b5099 "Fix initrd/dtb
interaction" put the new code outside of the #if defined(CONFIG_OF_LIBFDT)
when it should have gone inside of the conditional. As a result, it
broke non-LIBFDT board builds.
Also added a missing "not." to the comment.

The original code would wrongly relocate the blob to be right before
the initrd if it existed. The blob *must* be within CFG_BOOTMAPSZ,
if it is defined. So we make two changes:
1) flag the blob for relocation whenever its address is above BOOTMAPSZ
2) If the blob is being relocated, relocate it before kbd, not initrd

The last fdt patch to bootm did board setup based on the address
specified by a prior fdt address command invocation. The bootm
code, as its call to fdt_chosen does, should use the fdt specified
by the user on the bootm command. Note this restores full
functionality for the 8360's existing default boot environment
values, e.g. 'run nfsboot' (i.e. no having to 'fdt addr $fdtaddr'
before booting a kernel).

In the patch titled "Create new fdt boardsetup command..." I removed the
call to ft_board_setup() from the routine fdt_chosen(), but I forgot
to add a direct call back into cmd_bootm.c
This fixes the oversight by adding the direct call to the bootm command.

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.
All transformations are of the form:
Before:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)
