Routine Description:
The main function used to send the command to the card inserted into the SD host
slot.
It will assemble the arguments to set the command register and wait for the command
and transfer completed until timeout. Then it will read the response register to fill
the ResponseData
Arguments:
This - Pointer to EFI_SD_HOST_IO_PROTOCOL
CommandIndex - The command index to set the command index field of command register
Argument - Command argument to set the argument field of command register
DataType - TRANSFER_TYPE, indicates no data, data in or data out
Buffer - Contains the data read from / write to the device
BufferSize - The size of the buffer
ResponseType - RESPONSE_TYPE
TimeOut - Time out value in 1 ms unit
ResponseData - Depending on the ResponseType, such as CSD or card status
Returns:
EFI_SUCCESS
EFI_INVALID_PARAMETER
EFI_OUT_OF_RESOURCES
EFI_TIMEOUT
EFI_DEVICE_ERROR
