2014-05-13ARM: tegra: set CONFIG_SYS_MMC_MAX_DEVICEStephen Warren
If CONFIG_API is ever to be enabled on Tegra, this define must be set, since api/api_storage.c uses it. A couple of annoyting things about CONFIG_SYS_MMC_MAX_DEVICE 1) It isn't documented in README. The same is true for a lot of similar defines used by api_storage.c. 2) It doesn't represent MAX_DEVICE but rather NUM_DEVICES, since the valid values are 0..n-1 not 0..n.

2014-04-02mmc: fsl_esdhc: fix calculation of timeout for data transactionsAndrew Gabbasov
Calculation of the timeout value should be based on actual clock value, written to controller registers. Since mmc->tran_speed is either the maximum allowed speed, or the preliminary value, that is be not yet set to registers, the actual timeout, taken by the controller, based on its clock settings, may be much longer than expected, based on mmc->tran_speed value. In particular it happens at early initialization stage, when typical value of mmc->tran_speed is 20MHz or 26MHz, while actual clock setting, configured in the controller, is 400kHz. It's more correct to use mmc->clock value for timeout calculation instead. Signed-off-by: Andrew Gabbasov <andrew_gabbasov@mentor.com> Acked-by: Pantelis Antoniou <panto@antoniou-consulting.com>

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>

Tegra124's MMC controller is very similar to earlier SoC generations, and can be supported by the same driver. However, there are some non-backwards-compatible HW differences, and hence a new DT compatible value must be used to describe the HW. This patch updates the driver to support that new compatible value. That said, the HW differences are only relevant when enabling certain high-performance transfer modes. Since the driver is currently very simple and doesn't enable those modes, we don't actually need to address any of these HW differences in the code yet, hence the simple nature of this patch.

2014-01-09mmc: add setdsr supportMarkus Niebel
The eMMC and the SD-Card specifications describe the optional SET_DSR command. During measurements at our lab we found that some cards implementing this feature having really strong driver strengts per default. This can lead to voltage peaks above the specification of the host on signal edges for data sent from a card to the host. Since availability of a given card type may be shorter than the time a certain hardware will be produced it is useful to have support for this command (Alternative would be changing termination resistors and adapting the driver strength of the host to the used card.) Following proposal for an implementation: - new field that reflects CSD field DSR_IMP in struct mmc - new field for design specific DSR value in struct mmc - board code can set DSR value in mmc struct just after registering an controller - mmc_startup sends the the stored DSR value before selecting a card, if DSR_IMP is set Additionally the mmc command is extended to make is possible to play around with different DSR values. The concept was tested on a i.MX53 based platform using a Micron eMMC card where the default DSR is 0x0400 (12mA) but in our design 0x0100 (0x0100) were enough. To use this feature for instance on a mx53loco one have to add a call to mmc_set_dsr() in board_mmc_init() after calling fsl_esdhc_initialize() for the eMMC.
