[PATCH 0/2] omapfb: option to use coherent dma mem

Hi,

This is a bit refined version from the patch sent by Ivaylo.

So Ivaylo asked for an exclusive memory area for omapfb, so that the
allocations would not fail, and Vaibhav asked for reserving the fb at a
specified physical address, so that the bootloader can pass the fb to the
kernel. Those are a bit linked issues, and these patches try to accomplish
both.

This series is somewhat experimental, as I'm not so familiar with the dma api,
but, well, this seemed to work for the tests I did.
