Converts from: struct mmc_request mrq; memset(&mrq, 0, sizeof(struct mmc_request)); to: struct mmc_request mrq = {0}; because it's shorter, as performant, and easier to work out whether initialization has happened. Signed-off-by: NChris Ball <cjb@laptop.org>

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.

Not architecture specific code should not #include <asm/scatterlist.h>. This patch therefore either replaces them with #include <linux/scatterlist.h> or simply removes them if they were unused. Signed-off-by: NAdrian Bunk <bunk@kernel.org> Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

Teach the MMC/SD/SDIO core about using SPI mode. - Use mmc_host_is_spi() so enumeration works through SPI signaling and protocols, not just the native versions. - Provide the SPI response type flags with each request issued, including requests from the new lock/unlock code. - Understand that cmd->resp[0] and mmc_get_status() results for SPI return different values than for "native" MMC/SD protocol; this affects resetting, checking card lock status, and some others. - Understand that some commands act a bit differently ... notably: * OP_COND command doesn't return the OCR * APP_CMD status doesn't have an R1_APP_CMD analogue Those changes required some new and updated primitives: - Provide utilities to access two SPI-only requests, and one request that wasn't previously needed: * mmc_spi_read_ocr() ... SPI only * mmc_spi_set_crc() ... SPI only (override by module parm) * mmc_send_cid() ... for use without broadcast mode - Updated internal routines: * Previous mmc_send_csd() modified into mmc_send_cxd_native(); it uses native "R2" responses, which include 16 bytes of data. * Previous mmc_send_ext_csd() becomes new mmc_send_cxd_data() helper for command-and-data access * Bugfix to that mmc_send_cxd_data() code: dma-to-stack is unsafe/nonportable, so kmalloc a bounce buffer instead. - Modified mmc_send_ext_csd() now uses mmc_send_cxd_data() helper - Modified mmc_send_csd(), and new mmc_spi_send_cid(), routines use those helper routines based on whether they're native or SPI The newest categories of cards supported by the MMC stack aren't expected to work yet with SPI: MMC or SD cards with over 4GB data, and SDIO. All those cards support SPI mode, so eventually they should work too. Signed-off-by: NDavid Brownell <dbrownell@users.sourceforge.net> Signed-off-by: NPierre Ossman <drzeus@drzeus.cx>

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.
