Good catch, didn't know this routine exists. Will fix it in v3.

Unneeded.
If you remove that inclusion, build will fail with errors like this:
include/android_image.h:28:2: error: unknown type name ‘u32’
So it should be included either in android_image.h, or I should include it in common/fb_mmc.c *before* including android_image.h. Which is (I presume) a bad style. So I incline to do that the way I did it. If you still don't agree -- I'll rework it.

Just use ALIGN() in the code you're writing? This is for things we're pulling directly from Linux really.
Thought it would be more clear that way. Btw, I pulled PAGE_ALIGN() from kernel (from include/linux/mm.h). But it's not important to me, so if you want me to use ALIGN() -- I will change it in v3.
Thanks!
