-Subject: of/mips: Add device tree support to MIPS
-X-Git-Tag: v2.6.37-rc1~129^2~3

-of/mips: Add device tree support to MIPS
-
-Add the ability to enable CONFIG_OF on the MIPS architecture.

-Signed-off-by: Dezhong Diao <dediao@cisco.com>
-[grant.likely@secretlab.ca: cleared out obsolete hooks,
-	removed ARCH_HAS_DEVTREE_MEM,
-	remove __init tags from header file,
-	removed debugfs support hunk]
-[ddaney@linux-mips.org: backed out over aggressive trimming of hooks]
-Acked-by: Ralf Baechle <ralf@linux-mips.org>
-Tested-by: David Daney <ddaney@caviumnetworks.com>
