> Add dma api driver").  Maybe this depends on a particular architecture?

This driver is for any platform that has the ARM's Primcell DMAC
PL330. So there is no dependency on ARCH_xxxx
Any platform with such a DMAC should select PL330 and this driver
had better be build depending upon PL330 rather than selecting  PL330.

Something like...

config PL330_DMA
       tristate "DMA API Driver for PL330"
       select DMA_ENGINE
-       select PL330
+      depends on PL330
       help
         Select if your platform has one or more PL330 DMACs.
         You need to provide platform specific settings via
         platform_data for a dma-pl330 device.

I am not aware of how such issues are fixed at this stage, please
let me know what is expected of me.

Regards.
