Direct Memory Access (DMA) Support
To control the mappings:
OMAP 3.2 Mapping: DMA_CCR.OMAP3_1_Mapping_Disable = 1
OMAP 3.1 Mapping: DMA_CCR.OMAP3_1_Mapping_Disable = 0
See the Multimedia Processor Interrupts Reference Guide (SPRU757) for
more details about interrupts.

In case of simultaneous events in two physical channels that share the same
interrupt line, only one interrupt is generated and all the relevant status bits are
set.
Each physical channel has a seven-bit status register. When an interrupt is
shared by two logical channels, the MPU can read the status from the two
channels in one TIPB access. The data read has the format shown in
Figure 11.
