[Domenico Andreoli]

From: Domenico Andreoli <domenico.andreoli at linux.com>

Add new targets to build zImage and uImage with DTB appended (i.e. make
'uImage-dtb.am335x-bone' or 'make zImage-dtb.omap3-evm').

Is this a better moment for this patch?

Anyway, here is an update for v3.5-rc4. Added zImage-dtb.* as a valid
target and the .gitignore entries.

cheers
Domenico
