ppc: Allow boards to specify effective amount of memory
For historical reasons we limited the stack to 256M because some boards
could only map that much via BATS. However newer boards are capable of
mapping more memory (for example 85xx is capable of doing up to 2G).

error check autoconf.mk generation
If any of the steps for generating autoconf.mk fail currently, they go
unnoticed. To fix, we can simply add 'set -e' to the long list of commands.
This is simpler and more robust than placing '|| exit $$?' after every line.

easylogo: clean up some more and add -r (rgb) support
Michael Hennerich added support for outputting an image in RGB format rather
than forcing YUYV all the time. This makes obvious sense if the display you
have takes RGB input rather than YUYV.
Rather than hack in support for options, I've converted it to use getopt and
cleaned up the argument parsing in the process.

Makefile: add target for $(LDSCRIPT)
If the $(LDSCRIPT) does not exist (normally it's board/$(BOARD)/u-boot.lds),
then change into the board directory and try and create it. This allows you
to generate the linker script on the fly based upon board defines (like the
Blackfin boards do).
There should be no regressions due to this change as the normal case is to
already have a u-boot.lds file. If that's the case, then there's nothing to
generate, and so make will always exit. The fix here is that if the linker
script does not exist, the implicit rules take over and attempt to guess how
to generate the file.

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.

The option CONFIG_I2C_MULTI_BUS does not have any effect on Sequoia, the

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.
