BenH still need to ACK this though.
From: Nikunj A. Dadhania <nikunj@linux.vnet.ibm.com>
* Determines size of the flash using device tree.
* Provides nvram access functions for RTAS_NVRAM
* Allocates temporary buffer of nvram in SLOF code and use that in C.
(sbrk not available)
* NVRAM_LENGTH is used at various places, make sure it is well guarded
and also use dynamically determined size once an RTAS-NVRAM is
found.
* Use NVRAM_LENGTH as a variable in case of RTAS_NVRAM, not very
elegant though

Changelog from v1:
* #define cleanups suggested by Thomas/Benh
* Fix makefile which missed passing $FLAG for building llfw
* renamed vio-nvram.fs as rtas-nvram.fs

These two compiler flags for additional warnings help to improve the quality
of the source code: Removed some unused code and fixed some obvious bugs.

The compiler flags -Wmissing-prototypes and -Wstrict-prototypes generally help
to write code with proper prototypes. This way one can avoid some ugly bugs
because it helps to identify functions that do not have prototypes in headers.
It also helps to improve performance since local functions then have to be
declared "static", so the compiler can do better optimizations.

When building SLOF from a git repository, use the SHA-id as version information
instead of the less useful "private build" string.
Also make sure that version information is updated during each build, so that
we also print more accurate "build date" information now.

GCC 4.6 complains about unused-but-set variables - which can safely be removed
in our cases.
Also fixed a strict-aliasing problem in rtas_flash.c of board-js2x.

Cleaned up the toc-relative assembly of net-snk, fixed the Makefiles, save the
modules as ELF files instead of raw binaries, adjust the net-snk base address
and the load-base variable... a lot of changes were required to make the net-snk
and the snk modules relocatable, too. But now it should be possible to relocate
all files so that the firmware also runs with less than 256 MiB RAM.

Provide a IMA (initially mapped area) value to Paflof so that the Forth code
can properly claim the memory regions which are used by Paflof.

Split elf.c into elf32.c and elf64.c for better readability. Added relocation
code to libelf for 64-bit ELF images, modified the Paflof Makefile to link
the executable with relocation information and load Paflof now to the upper
end of the memory.
