SDIO controller/MMC card interface
The SDIO host controller has an AMBA compatible interface and conforms to the SD host
controller standard specification version 2.0. It handles SD/SDIO protocol at transmission
level, packing data, adding cyclic redundancy check (CRC), start/end bit, and checking for
transaction format correctness.
