      iop3xx: surface the iop3xx DMA and AAU units to the iop-adma driver · 2492c845
      Dan Williams 提交于
      Adds the platform device definitions and the architecture specific support
      routines (i.e. register initialization and descriptor formats) for the
      iop-adma driver.
      
      Changelog:
      * add support for > 1k zero sum buffer sizes
      * added dma/aau platform devices to iq80321 and iq80332 setup
      * fixed the calculation in iop_desc_is_aligned
      * support xor buffer sizes larger than 16MB
      * fix places where software descriptors are assumed to be contiguous, only
        hardware descriptors are contiguous for up to a PAGE_SIZE buffer size
      * convert to async_tx
      * add interrupt support
      * add platform devices for 80219 boards
      * do not call platform register macros in driver code
      * remove switch() statements for compatible register offsets/layouts
      * change over to bitmap based capabilities
      * remove unnecessary ARM assembly statement
      * checkpatch.pl fixes
      * gpl v2 only correction
      * phys move to dma_async_tx_descriptor

      [ARM] 4348/4: iop3xx: Give Linux control over PCI initialization · e90ddd81
      Dan Williams 提交于
      Currently the iop3xx platform support code assumes that RedBoot is the
      bootloader and has already initialized the ATU.  Linux should handle this
      initialization for three reasons:
      
      1/ The memory map that RedBoot sets up is not optimal (page_to_dma and
      virt_to_phys return different addresses).  The effect of this is that using
      the dma mapping API for the internal bus dma units generates pci bus
      addresses that are incorrect for the internal bus.
      
      2/ Not all iop platforms use RedBoot
      
      3/ If the ATU is already initialized it indicates that the iop is an add-in
      card in another host, it does not own the PCI bus, and should not be
      re-initialized.
      
      Changelog:
      * rather than change nr_controllers to zero, simply do not call
        pci_common_init
