This patch fixes a couple of missing dependencies in
arch/powerpc/boot/Makefile.  First, it ensures that the zlib.h header
is linked in before attempting to build gunzip_util.o, as it is,
building gunzip_util.o usually works, but not always depending on make
order.

Second, it makes the final images which are built using a dts
dependent on that dts, so the image will be correctly rebuilt if the
dts changes.  This in turn requires fixing the definition of the dts
variable.  CONFIG_DEVICE_TREE from Kconfig will have quotes around it,
which don't matter when passing the variable to a shell, but which
need to be removed when incorporating it into a filename for make's
use.

This patch makes a few small cleanups to the cuboot code.
	- It removes the double layered selection of images, via
cuboot-plat-y, instead having the cuboot platforms directly select a
suitable image-y (this changes the name of the final cuboot image from
plain cuImage to cuImage.<platform>).
	- Factors out some code in the wrapper that's potentially
useful to platforms other than uboot.

This fixes a few bugs in how dt_xlate_reg() handles address arrays:

1. copy_val() was copying into the wrong end of the array, resulting
in random stack garbage at the other end.
2. dt_xlate_reg() was getting the result from the wrong end of the array.
3. add_reg() and sub_reg() were treating the arrays as
little-endian rather than big-endian.
4. add_reg() only returned an error on a carry out of the entire
array, rather than out of the naddr portion.
5. The requested reg resource was checked to see if it exceeded
the size of the reg property, but not to see if it exceeded the
size of the buffer.

Commit 79c85419 introduced code to move
the initrd if it was in a place where it would get overwritten by the
kernel image.  Unfortunately this exposed the fact that the code that
checks whether the values passed in r3 and r4 are intended to indicate
the start address and size of an initrd image was not as thorough as the
kernel's checks.  The symptom is that on OF-based platforms, the
bootwrapper can cause an exception which causes the system to drop back
into OF.

Previously it didn't matter so much if the code incorrectly thought that
there was an initrd, since the values for start and size were just passed
through to the kernel.  Now the bootwrapper needs to apply the same checks
as the kernel since it is now using the initrd data itself (in the process
of copying it if necessary).  This adds the code to do that.

This cleans up how the zImage code manipulates the kernel
command line.  Notable improvements from the old handling:
	- Command line manipulation is consolidated into a new
prep_cmdline() function, rather than being scattered across start()
and some helper functions
	- Less stack space use: we use just a single global command
line buffer, which can be initialized by an external tool as before,
we no longer need another command line sized buffer on the stack.
	- Easier to support platforms whose firmware passes a
commandline, but not a device tree.  Platform code can now point new
loader_info fields to the firmware's command line, rather than having
to do early manipulation of the /chosen bootargs property which may
then be rewritten again by the core.

This patch adds a library of useful device tree manipulation functions
to the zImage library, for use by platform code.  These functions are
based on the hooks already in dt_ops, so they're not dependent on a
particular device tree implementation.  This patch also slightly

This is a consolidation of my work in this area with Scott Wood's
