David Gibson 2f0dfeaa84 [POWERPC] Use embedded libfdt in the bootwrapper
This incorporates libfdt (from the source embedded in an earlier
commit) into the wrapper.a library used by the bootwrapper.  This
includes adding a libfdt_env.h file, which the libfdt sources need in
order to integrate into the bootwrapper environment, and a
libfdt-wrapper.c which provides glue to connect the bootwrapper's
abstract device tree callbacks to the libfdt functions.

In addition, this changes the various wrapper and platform files to
use libfdt functions instead of the older flatdevtree.c library.

Scott Wood 2f1d489932 [POWERPC] bootwrapper: Move linker symbols into ops.h
Most of these were previously used by numerous C files and
redeclared in each one.

David Gibson 85aecac8d2 [POWERPC] Consolidate cuboot initialization code
The various cuboot platforms (i.e. pre-device tree aware u-boot for
83xx, 85xx and Ebony) share a certain amount of code for parsing the
boot parameters.  To a certain extent that's inevitable, since they
platforms have different definitions of the bd_t structure.  However,
with some macro work and a helper function, this patch improves the
situation a bit.

In the process, this fixes a bug on Ebony, which was incorrectly
handling the parameters passed form u-boot for the command line (the
bug was copied from 83xx and 85xx which have subsequently been fixed).

Scott Wood dab4d7984e [POWERPC] U-boot passes the initrd as start/end, not start/size.
The boot wrapper platform init code on 83xx and 85xx using the cuboot
platform type was incorrectly assuming that u-boot supplied the size
of the initrd, whereas it actually supplies the end address.  This
fixes it.

Scott Wood 173ba87b95 [POWERPC] bootwrapper: cuboot-83xx: Exclude upper 1MB from heap.
The uppermost part of memory is where u-boot puts the stack, so don't
include that in the heap.  It's not currently causing problems, as the
current code allocates from the bottom of the heap, but this will keep
things from potentially breaking if a future implementation were to
allocate from the top.

Scott Wood 5cc5133a29 [POWERPC] bootwrapper: cuboot for 83xx
This adds cuboot support for MPC83xx platforms.

A device tree used with this must have linux,stdout-path in /chosen and
linux,network-index in any network device nodes that need mac addresses
assigned.
