[new uImage] Add dual format uImage support framework
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.

[new uImage] Add fit_parse_conf() and fit_parse_subimage() routines
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.

Fix CPU POST test failure
The CPU POST test code (run from cpu_post_exec_31()) doesn't follow the
ABI carefully, at least the CR3, CR4, and CR5 fields of CR are clobbered
by it. The gcc-4.2 with its more aggressive optimization exposes this fact.
This patch just saves the CR value before running the test code, so allowing
it to do anything it wants with CR.

PPC440EPx: Optionally enable second I2C bus
The option CONFIG_I2C_MULTI_BUS does not have any effect on Sequoia, the
PPC440EPx reference platform, because IIC1 is never enabled. Add Sequoia board
code to turn on IIC1 if CONFIG_I2C_MULTI_BUS is selected.

ppc4xx: HCU4/5. Cleanups
- Fix some coding style violations.
- Use in/out_u16/32 where appropriate.
- Use register names from ppc405.h.
- Fix trace useage for Lauterbach.
- Remove obsolete generation HCU2.
- Renamed fixed_hcu4_sdram to init_ppc405_sdram.
If the length of the memory address range passed to the "mtest" command is

only update version header as needed
Constantly rebuilding the version header will force useless relinking, so we
simply need to compare the new header with the existing one before updating
it.

PPC: Use r2 instead of r29 as global data pointer
R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc
will refuse to use load/store multiple insns; instead, it issues a
list of simple load/store instructions upon function entry and exit,
resulting in bigger code size, which in turn makes the build for a
few boards fail.
common/miiphyutil.c: Cleanup MII_DEBUG and debug()
Current MII_DEBUG is confusing in two ways. One is useless define-then-
undef at the top of the file. The other is there is only one debug() in
this file, and that doesn't seem worthwhile to bother having MII_DEBUG.
While there are many useful printf()/puts() debug codes, but they are for
DEBUG, not for MII_DEBUG.
This patch tries to put them all together into MII_DEBUG and debug().

OneNAND Initial Program Loader (IPL) support
This patch enables the OneNAND boot within U-Boot.
Before this work, we used another OneNAND IPL called X-Loader based
on open source. With this work, we can build the oneboot.bin image
without other program.
The build sequence is simple.
First, it compiles the u-boot.bin
Second, it compiles OneNAND IPL
Finally, it becomes the oneboot.bin from OneNAND IPL and u-boot.bin
The mechanism is similar with NAND boot except it boots from itself.
Another thing is that you can only use the OneNAND IPL only to work
other bootloader such as RedBoot and so on.

Fix CONFIG_MMC usage in fat code
A #if statement in fat.c depended on CONFIG_MMC, instead of

Remove #undef DEBUG from MPC83xx board header files
Remove the "#undef DEBUG" line from all Freescale 83xx board header files.
The inclusion of this line makes it impossible to enable debug code in
other source files, because "#define DEBUG" typically needs to be defined
before any header files are included.
