ARM: 6132/1: PL330: Add common core driver
PL330 is a configurable DMA controller PrimeCell device. The register map of the device is well defined. The configuration of a particular implementation can be read from the six configuration registers CR0-4,Dn. This patch implements a driver for the specification:- http://infocenter.arm.com/help/topic/com.arm.doc.ddi0424a/DDI0424A_dmac_pl330_r0p0_trm.pdf The exported interface should be sufficient to implement a driver for any DMA API.
