    Eric Miao authored
    1. introduce folder of 'arch/arm/plat-pxa' for common code across different
       PXA processor families
    2. initially moved DMA code into plat-pxa
    3. common code in <mach/dma.h> moved into <plat/dma.h>, new processors
       should implement its own <mach/dma.h>, provide the following required
       definitions and '#include <plat/dma.h>' in the end:
       - DMAC_REGS_VIRT for mapped virtual address of the DMA registers'
         physical I/O memory
