One major difference is that the PL310 can have up to 16 ways. This change uses the cache's part ID and the Associativity bits in the AUX_CTRL register to determine the number of ways. Also, this version prints out the CACHE_ID and AUX_CTRL registers. Acked-by: Will Deacon Acked-by: Acked-by: Catalin Marinas Signed-off-by: Jason S.

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.
