2014-03-24mmc: Split mmc struct, rework mmc initialization (v2)Pantelis Antoniou
The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long. Changes since v1: * Use calloc instead of manually calling memset. * Mark mmc_register as deprecated. Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com>
2014-03-24mmc: Convert mmc struct's name array to a pointerPantelis Antoniou
Using an array is pointless; even more pointless (and scary) is using sprintf to fill it without a format string. Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com>
2014-03-24mmc: Remove ops from struct mmc and put in mmc_opsPantelis Antoniou
Remove the in-structure ops and put them in mmc_ops with a constant pointer to it. This makes the mmc structure smaller as well as conserving code space (in theory). All in-tree drivers are converted as well; this is done in a single patch in order to not break git bisect. Changes since V1: Fix compilation b0rked issue on omap platforms where OMAP_GPIO was not set. Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com>

2012-09-06mmc: Remove incorrect cmd->flags usageAndy Fleming
There were a couple of drivers that were actually using the flags field of the cmd structure, despite the fact that no one ever *set* that field. When we removed the field, those drivers failed to compile. Replaced the references with the correct usage of resp_type. Signed-off-by: Andy Fleming <afleming@freescale.com>
2012-09-01u8500: Separating mmc config parameters from driverJohn Rigby
Configuration in vexpress and u8500.v1 is different from what is needed in u8500.v2. As such, card configuration specifics need to reside in the board file rather than the driver.

2012-01-08mmc: Implement card detection.Thierry Reding
Check for card detect each time an MMC/SD device is initialized. If card detection is not implemented, this code behaves as before and continues assuming a card is present. If no card is detected, has_init is reset for the MMC/SD device (to force initialization next time) and an error is returned.

2011-11-08MMC: PL180: Fix infinite loop with VExpress extended fifo implementationJon Medhurst (Tixy)
The new IO FPGA implementation for Versatile Express contains an MMCI (PL180) cell with the FIFO extended to 128 words. This causes the read_bytes() function to go into an infinite loop; as it will wait for for the half-full signal (SDI_STA_RXFIFOBR) if there are more than 8 words remaining (SDI_FIFO_BURST_SIZE), but it won't receive this signal once there are fewer than 64 words left to transfer. One possible fix is to add some build time configuration to change SDI_FIFO_BURST_SIZE for the new implementation. However, the problematic code only seems to exist as a small performance optimisation, so the solution implemented by this patch is to simply remove it. The error checking following the loop is also removed as this will be handled by code further down the function.

2011-04-29MMC: make b_max unconditionalJohn Rigby
Make existing field b_max field in struct mmc unconditional and use it instead of CONFIG_SYS_MMC_MAX_BLK_COUNT in mmc_bread and mmc_bwrite. Initialize b_max to CONFIG_SYS_MMC_MAX_BLK_COUNT in mmc_register if it has not been initialized by the hw driver. Initialize b_max to 0 in all callers to mmc_register.
