[dirk.brandewie at gmail.com]

From: Dirk Brandewie <dirk.brandewie at gmail.com>

This patch set adds the ability to link device tree blobs into
vmlinux. 

Patch 1 implements the changes to include/asm-generic/vmlinux.lds.h and
adds a generic rule for generating DTB objects to be linked vmlinux.

Patch 2 implements linking a DTB into an x86 image.

Patch 3-4 move {powerpc,microblaze}/boot/Makefile to use the dtc rule
in patch 1.

This patch set has been tested on x86.

Powerpc and Microblaze have been compile tested with and without patch
3 and 4 applied.

Changes from V1:

Documentation added for dtc command in Makefile.lib to
Documentation/kbuild/makefiles.txt
Separate DTB_ALIGNMENT define removed.
FORCE removed from dtc rule.
Removed hardcoded path to dts files from dtc command.  
Moved %.dtb: %.dts rule to arch specific makefiles. 
 
Patch for adding kernel command line option to pass in dtb_compat
string dropped from this set will be submitted seperately.

Changes from V2:

Rule to create assembly wrapper for blob changed to use Sam Ravnborgs
suggested implementation.

Rules in architecture specific Makefiles changed to use the cmd
function instead of the if_changed function.
