Hi!
Commit
commit 499cd8298628eeabf0eb5eb6525d4faa0eec80d8 Author: Grant Likely <grant.likely@secretlab.ca> Date: Tue Nov 27 16:29:11 2012 -0700
The current rules have the .dtb files build in a different directory from the .dts files. The only reason for this is that it was what PowerPC has done historically. This patch changes ARM to use the generic dtb rule which builds .dtb files in the same directory as the source .dts.

Moves dtb files from arch/arm/boot/ to arch/arm/boot/dtb. That causes several problems:
1) it is inconsistent with 3.8, making switching between 3.9-rc1 and 3.8 tricky
2) what is worse, it is very easy to do stuff like
make socfpga_cyclone5.dtb
and you end up with success, but stale file in arch/arm/boot, where your scripts expect it.
(There are some attempts to rm stale files in Makefiles; they don't work in above case).
3) it is now incosistent between powerpc and arm.
4) device tree _binary_ files are now output in device tree _source_ directory
(Sorry for noticing this earlier).
I believe the commit should be simply reverted. Reasons to move dtbs around are not good enough. Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
