2014-12-12mmc: dw_mmc: Use active DDR mode flagAndrew Gabbasov
The card_caps bit should denote the card capability to use DDR mode, but we need the flag indicating that the DDR mode is active. Signed-off-by: Andrew Gabbasov <andrew_gabbasov@mentor.com>
2014-12-12mmc: Fix block length for DDR modeAndrew Gabbasov
Block length for write and read commands is fixed to 512 bytes when the card is in Dual Data Rate mode. If block length read from CSD is different, make sure the driver will use correct length in all further calculations and settings. Signed-off-by: Andrew Gabbasov <andrew_gabbasov@mentor.com>
2014-12-12mmc: Fix Dual Data Rate capability recognitionAndrew Gabbasov
Since the driver doesn't work in 1.2V or 1.8V signaling level modes, Dual Data Rate mode can be supported by the driver only if it is supported by the card in regular 3.3V mode. So, check for a particular single bit in card type field. Signed-off-by: Andrew Gabbasov <andrew_gabbasov@mentor.com>
2014-12-12mmc: Fix handling of bus widths and DDR card capabilitiesAndrew Gabbasov
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>

2014-12-04omap_hsmmc: Board-specific TWL4030 MMC power initializationsPaul Kocialkowski
Boards using the TWL4030 regulator may not all use the LDOs the same way (e.g. MMC2 power can be controlled by another LDO than VMMC2). This delegates TWL4030 MMC power initializations to board-specific functions, that may still call twl4030_power_mmc_init for the default behavior.

U-Boot has never cared about the type when we get max/min of two values, but Linux Kernel does. This commit gets min, max, min3, max3 macros synced with the kernel introducing type checks. Many of references of those macros must be fixed to suppress warnings.

2014-11-06omap: hsmmc: assume cd gpio is active lowIgor Grinberg
Switch the default CD GPIO polarity to active low. The current hsmmc driver assumption that the CD GPIO is active high, but in the real hardware, usually the opposite holds. The usual SD card socket has a mechanical switch which is grounded as soon as a card is inserted. Of course there might be some board logic which inverts the signal, but as far as current users are concerned, there is no such logic. Current U-Boot users either not using the CD functionality, or have a different way (e.g. external to SoC GPIO controller) for checking the card presence. This patch also brings the polarity assumption in line with the Linux kernel and adds appropriate comments. This patch also might spare issues once the TWL GPIO driver will be converted to the DM.

sunxi SOCs can boot from both mmc0 and mmc2, detect from which one we're booting, and make that one "mmc dev 0" so that a single u-boot binary can be used for both the onboard eMMC and for external sdcards. When we're booting from mmc2, we make it dev 0 because that is where the SPL will load the tertiary payload (the actual u-boot binary in our case) from, see: common/spl/spl_mmc.c, which has dev 0 hardcoded everywhere.

During rigorous testing of our latest update infrastructure I came across quite consistent timeouts on certain eMMC parts (e.g. Hynix H26M21001ECR) when writing big (e.g. in excess of 400 MB) file system images: MMC write: dev # 0, block # 40960, count 944128 ... mmc_send_cmd_bounced: MMC Timeout Interrupt status 0x00000001 Interrupt status enable 0xdfff003b Interrupt signal enable 0xdfff0002 Present status 0x01870106 mmc write failed Comparing the various data sheets I came across the following timeout specification: Secure Erase/TRIM Timeout=300ms*2*10=6000ms Unfortunately empirical testing still failed albeit much more rarely. Increasing the timeout to 8000ms made it finally disappear entirely. This patch allows us writing various eMMC parts without seeing any further issues.
