BCM2838 DMA control/status BCM2838_DMA_CS_*

See: Section 4

`BCM2838_DMA_CS_ACTIVE = (1 shl 0);`	Activate the DMA (This bit enables the DMA. The DMA will start if this bit is set and the CB_ADDR is non zero. The DMA transfer can be paused and resumed by clearing, then setting it again.)
`BCM2838_DMA_CS_END = (1 shl 1);`	DMA End Flag (Set when the transfer described by the current control block is complete. Write 1 to clear.)
`BCM2838_DMA_CS_INT = (1 shl 2);`	Interrupt Status (This is set when the transfer for the CB ends and INTEN is set to 1. Write 1 to clear.)
`BCM2838_DMA_CS_DREQ = (1 shl 3);`	DREQ State (Indicates the state of the selected DREQ (Data Request) signal, ie. the DREQ selected by the PERMAP field of the transfer info.)
`BCM2838_DMA_CS_PAUSED = (1 shl 4);`	DMA Paused State (Indicates if the DMA is currently paused and not transferring data)
`BCM2838_DMA_CS_DREQ_PAUSED = (1 shl 5);`	DMA Paused by DREQ State (Indicates if the DMA is currently paused and not transferring data due to the DREQ being inactive)
`BCM2838_DMA_CS_WAITING_FOR_OUTSTANDING_WRITES = (1 shl 6);`	DMA is Waiting for the Last Write to be Received (Indicates if the DMA is currently waiting for any outstanding writes to be received, and is not transferring data.)
Bit 7 Reserved - Write as 0, read as don't care
`BCM2838_DMA_CS_ERROR = (1 shl 8);`	DMA Error (Indicates if the DMA has detected an error)
`BCM2838_DMA_CS_PRIORITY = ($F shl 16);`	AXI Priority Level (Sets the priority of normal AXI bus transactions. Zero is the lowest priority.)
`BCM2838_DMA_CS_PANIC_PRIORITY = ($F shl 20);`	AXI Panic Priority Level (Sets the priority of panicking AXI bus transactions)
Bits 24:27 Reserved - Write as 0, read as don't care
`BCM2838_DMA_CS_WAIT_FOR_OUTSTANDING_WRITES = (1 shl 28);`	Wait for outstanding writes (When set to 1, the DMA will keep a tally of the AXI writes going out and the write responses coming in.)
`BCM2838_DMA_CS_DISDEBUG = (1 shl 29);`	Disable debug pause signal (When set to 1, the DMA will not stop when the debug pause signal is asserted.)
`BCM2838_DMA_CS_ABORT = (1 shl 30);`	Abort DMA (Writing a 1 to this bit will abort the current DMA CB. The DMA will load the next CB and attempt to continue. The bit cannot be read, and will self clear.)
`BCM2838_DMA_CS_RESET = (1 shl 31);`	DMA Channel Reset (Writing a 1 to this bit will reset the DMA. The bit cannot be read, and will self clear.)

`BCM2838_DMA_CS_PRIORITY_DEFAULT = 0;`

BCM2838 DMA transfer information BCM2838_DMA_TI_*
