And thereby break the support. The IM-PD1 CLCD can only access the memory
on the IM-PD1. That's why the CLCD driver itself doesn't just allocate
the frame buffer using dma_alloc_writecombine(). Where the memory comes
from is platform specific. In this case...

It's a chunk of SRAM offset by the specified value and of the specified
