-  Abstractions for simple OMAP DMA. The DMA functions are modeled on 
-  the PCI IO protocol and follow the same rules as outlined in the UEFI specification.
-  OMAP_DMA4 structure elements are described in the OMAP35xx TRM. Currently 
-  there is no PCI'less DMA protocol, if one existed it could be used to
-  replace this library.
