The AT91 MCI has special SDIO transfer types: SDIO block and SDIO byte transfers, but at91_mci driver doesn't use them and handles all SDIO transfers as ordinary MMC block transfers. This causes problems for multiple-block SDIO transfers (in particular for 256-bytes blocks). Fix this situation by checking the opcode for SDIO CMD53 and setting the transfer type in the AT91_MCI_CMDR register properly. This patch was tested with libertas SDIO driver: problem with TX timeouts on big packets was eliminated.
