The problem we're facing is that next I will start adding DMA support for the U8500 and the MMCI derivate found in that platform doesn't *have* a PIO IRQ, which means the system cannot even boot without some solid DMA framework in place. (It is currently unbootable from the released kernels.) So unless there is some outstanding issue with this approach we pretty much need this now to keep working on mainlining the U8500. I would very much like to have the DMA patches for PrimeCell support pushed through Dan's tree, but that requires your ACKs of course, and it will inevitably collide with other PrimeCell patches for the next merge window (many submitted by myself admittedly). I can feed all the PrimeCell stuff to Dan if all agree that this is a good approach. Another approach is to apply the latest patches from Dan's tree to ARM and SPI alike and then feed the PrimeCell stuff through the ARM tree.
