From: Dirk Brandewie <dirk.brande...@gmail.com>
This patch adds linking device tree blobs into vmlinux. DTB's are
added by adding the blob object name to list of objects to be linked
into the image.
e.g:
obj-$(CONFIG_TEST_DTB) += test.dtb.o
The set of DTB linked into the image is controlled the Kconfig file
in arch/x86/kernel/dts/Kconfig
