[ARM] 3257/1: ixp2000: map in scratch and sram
Patch from Lennert Buytenhek For the ixp2000 netdev driver, we need to map in a chunk of SRAM (to store the transmit and receive descriptors) and the scratch get/put area (so that we can use the scratchpad rings in the cpu for managing the descriptors.) These are the final two mappings needed for the netdev driver and the last missing piece for the driver in mainline to work.
