Subject: [PATCH v2] arm/dt: Add a make rule to build dtb for enabled boards
Date: Mon,  4 Apr 2011 23:01:47 +0800	[thread overview]
Message-ID: <1301929307-1838-1-git-send-email-shawn.guo@linaro.org> (raw)

With 'make ARCH=arm dtb', it builds Device Tree Blobs for those boards
enabled by build CONFIG.

Signed-off-by: Shawn Guo <shawn.guo-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>

It's based on commit fe8e6d0b0e601ca0a63fe768d4b812d5a45a9da7
"arm/dt: Add dtb make rule" from Rob Herring.  And it works against
Linaro kernel tree.  But it needs to go through mainline review
before it gets applied.

Changes since v1:
* Take suggestion from Rob Herring to move .dts dection into machine
  sepcific Makefile.boot, so that arch/arm/boot/Makefile can be as
  clean as it is.
