* sdio: extend sdio_readsb() and friends to handle any length of bufferDavid Vrabel2007-09-23
| | | | | | | | | | | | | | | Extend sdio_readsb(), sdio_writesb(), sdio_memcpy_fromio(), and sdio_memcpy_toio() to handle any length of buffer by splitting the transfer into several IO_RW_EXTENDED commands. Typically, a transfer would be split into a single block mode transfer followed by a byte mode transfer for the remainder but we also handle lack of block mode support and the block size being greater than 512 (the maximum byte mode transfer size). host->max_seg_size <= host->max_req_size so there's no need to check both when determining the maximum data size for a single command.
