SD card controller
This controller conforms to the SD host controller standard specification version 2.0. It
handles SDIO/SD protocol at transmission level, packing data, adding cyclic redundancy
check (CRC), start/end bit, and checking for transaction format correctness.
The SD card controller provides programmed IO method and DMA data transfer method.
In the programmed IO method, the ARM processor transfers data using the buffer data port
register. Host controller support for DMA can be determined by checking the DMA support
in the capabilities register. DMA allows a peripheral to read or write memory without the
intervention from the CPU.
The system address register points to the first data address, and data is then accessed
sequentially from that address.
