iop3xx: surface the iop3xx DMA and AAU units to the iop-adma driver
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 Cc: Russell King <rmk@arm.linux.org.uk> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
