sdio: extend sdio_readsb() and friends to handle any length of buffer 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.

sdio: recognize io card without powercycle SDIO Simplified Specification V2.00 states that it is strongly recommended that the host executes either a power reset or issues a CMD52 (I/O Reset) to re-initialize an I/O only card or the I/O portion of a combo card. Additionally, the CMD52 must be issued first because it cannot be issued after a CMD0. With this patch the Nintendo Wii SDIO-based WLAN card is detected after a system reset, without requiring a complete system powercycle.
