    [POWERPC] PS3: System-bus rework · 6bb5cf10
    Geoff Levand authored
    Rework the PS3 system bus to unify device support.
     - DMA region sizes must be a power of two
     - storage bus DMA updates:
      - Small fixes for the PS3 DMA core:
          o fix alignment bug
          o kill superfluous test
          o indentation
          o spelling
          o export ps3_dma_region_{create,free}()
      - ps3_dma_region_init():
          o Add `addr' and `len' parameters, so you can create a DMA region that
            does not cover all memory (use `NULL' and `0' to cover all memory).
    	This is needed because there are not sufficient IOMMU resources to have
    	all DMA regions cover all memory.
          o Uninline
      - Added remove and shutdown routines to all drivers.
      - Added loadable module support to all drivers.
      - Added HV calls for iopte management (needed by sound driver).
