In certain board files, there are references to vram related functions

dependency, CONFIG_FB_OMAP2 should be a built-in feature.
arch/arm/plat-omap/include/plat/vram.h defines dummy inline function in
case vram.c is not compiled in, so the board files should compile fine.
As per the current architecture, CONFIG_FB_OMAP2 is dependent on
CONFIG_OMAP2_DSS. Hence CONFIG_OMAP2_DSS support should also be selected
by default.
The configuration is fine as it is. And anyway, if things do not compile
when something is configured as a module, the correct fix is hardly just
changing the feature to be compiled built-in =).
Agreed. :)
I am not an expert in DSS. I just wanted to raise my concern.

Compiles fine for me. Perhaps you are using some old kernel?
As mentioned in the cover letter, we get this error only if 2/2 is
applied and 1/2 is not applied.
I tested this by applying 2/2 on v3.0-rc4 and using omap2plus_defconfig.
