This patch depends on "genalloc: add a global pool list, allow to find pools by phys address", which provides the of_get_named_gen_pool function.

Your commit log doesn't mention that at all, and when I see things like that, I predict allyesconfig build failures, unless there is a similar dependency elsewhere that isn't visible in just the context of this patch alone. P.iram_alloc and iram_free are i.MX specific wrappers around gen_pool_alloc and gen_pool_free, located in <mach/iram.h>. Those were responsible for the dependency in the first place.
So when I do an allyesconfig for sparc, or parisc or alpha, and VIDEO_CODA gets selected, it will build just fine then? My point was that when you remove the ARCH_MXC dep, this probably gets opened up as a viable option to a _lot_ more platforms than you might want it exposed to. Paul. --
