MMC headers learn about SPI

2007-09-23T19:37:51+00:00

Teach the MMC/SD/SDIO system headers that some hosts use SPI mode - New host capabilities and status bits * MMC_CAP_SPI, with mmc_host_is_spi() test * mmc_host.use_spi_crc flag - SPI-specific declarations: * Response types, MMC_RSP_SPI_R* * Two SPI-only commands * Status bits used native to SPI: R1_SPI_*, R2_SPI_* - Fix a few (unrelated) whitespace bugs in the headers. - Reorder a few mmc_host fields, removing several bytes of padding None of these changes affect current code.

mmc: Separate out protocol ops

2007-05-01T11:04:18+00:00

Move protocol operations and definitions into their own files in an effort to separate protocol handling and bus arbitration more clearly. Signed-off-by: Pierre Ossman

Create a "core" subdirectory to house the central bus handling functions. Signed-off-by: Pierre Ossman

mmc: deprecate mmc bus topology

2007-05-01T11:04:18+00:00

The classic MMC bus was defined as multi card bus system, which is reflected in the design in the MMC layer. When SD showed up, the bus topology was abandoned and a star topology (one card per host) was mandated. MMC version 4 has followed this, officially deprecating the bus topology. As we do not have any known users of the bus topology we can remove support for it. This will simplify the code and rectify some incorrect assumptions in the newer additions.

mmc: Add support for SDHC cards

2007-02-04T19:54:07+00:00

Thanks to the generous donation of an SDHC card by John Gilmore, and the surprisingly enlightened decision by the SD Card Association to publish useful specs, I've been able to bash out support for SDHC. The changes are not too profound: i) Add a card flag indicating the card uses block level addressing and check it in the block driver. As we never took advantage of byte-level addressing, this simply involves skipping the block -> byte translation when sending commands. ii) The layout of the CSD is changed - a set of fields are discarded to make space for a larger C_SIZE. We did not reference any of the discarded fields except those related to the C_SIZE. iii) Read and write timeouts are fixed values and not calculated from CSD values. iv) Before invoking SEND_APP_OP_COND, we must invoke the new SEND_IF_COND to inform the card we support SDHC.

mmc: Correct definition of R6

2007-01-15T05:44:03+00:00

During development of SDHC support, it was discovered that the definition for R6 was incorrect. This patch fixes that and patches the drivers that do switch on the response type. Signed-off-by: Philip Langdale Cc: Alex Dubov Cc: Pavel Pisa Signed-off-by: Pierre Ossman
