Register Definitions

The SDMA controller contains separate LocalToHost (L2H) and HostToLocal (H2L)

channels that are independent of each other. These are used simultaneously thus

allowing full duplex transfer to occur.
The location of these registers are specified as a relative offset to a 512KB aligned

global PMMR offset. The default for the 512KB aligned offset is 0 FFD8 0000H defined

by the PMMRBAR register.
