* mmc: Fix handling of bus widths and DDR card capabilitiesAndrew Gabbasov2014-12-12-0/+1
| | | | | | | | | | | | | | | | | | | | | | | If the MMC_MODE_DDR_52MHz flag is set in card capabilities bitmask, it is never cleared, even if switching to DDR mode fails, and if the controller driver uses this flag to check the DDR mode, it can take incorrect actions. Also, DDR related checks in mmc_startup() incorrectly handle the case when the host controller does not support some bus widths (e.g. can't support 8 bits), since the host_caps is checked for DDR bit, but not bus width bits. This fix clearly separates using of card_caps bitmask, having there the flags for the capabilities, that the card can support, and actual operation mode, described outside of card_caps (i.e. bus_width and ddr_mode fields in mmc structure). Separate host controller drivers may need to be updated to use the actual flags. Respectively, the capabilities checks in mmc_startup are made more correct and clear. Also, some clean up is made with errors handling and code syntax layout. Signed-off-by: Andrew Gabbasov <andrew_gabbasov@mentor.com>

| * mmc: Split mmc struct, rework mmc initialization (v2)Pantelis Antoniou2014-03-24-9/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* mmc: add setdsr supportMarkus Niebel2014-01-09-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | When CONFIG_MMC_SPI is not enabled, the MMC_MODE_SPI capability can never be set. However there is code in mmc.c which uses the mmc_host_is_spi macro to check that capability & act accordingly. If we expand that macro to 0 when CONFIG_MMC_SPI is not set (since it will always be 0 at runtime anyway) then the compiler can optimize away the SPI-specific code paths in mmc.c.

* | mmc: Split device init to decouple OCR-polling delayChe-Liang Chiou2013-05-06-0/+30
|/ | | | | | | | | | | | | | | | | | | Most of time that MMC driver spends on initializing a device is polling OCR (operation conditions register). To decouple this polling loop, device init is split into two parts: The first part fires the OCR query command, and the second part polls the result. So the caller is now no longer bound to the OCR-polling delay; he may fire the query, go somewhere and then come back later for the result. To use this, call mmc_set_preinit() on any device which needs this. This can save significant amounts of time on boot (e.g. 200ms) by hiding the MMC init time behind other init.

The rationale for this change can be found in the following email thread: http://lists.denx.de/pipermail/u-boot/2011-November/110180.html In summary, the old API was not consistent with the rest of the MMC API which always passes a struct mmc as the first parameter.

The extra flag MMC_MODE_HC (high capacity) is added to indicate if the host is capable of handling the high capacity eMMC cards. Since this change is added to the generic mmc framework, then it requires other boards to indicate if their mmc controllers can handle high capacity cards.

(Refer to JESD84-A44.pdf/page 154) As bootloader may need to read out or reflashing images on those different partitions, it is better to enable the partition switch with console command support. Also for partition would be restore to user partition(part 0) when CMD0 is used, so change mmc_init routine to perform normal initialization only once for each slot, unless use the rescan command to force init again.
