- Avoid HS400 mode when accessing boot partitions
2019-06-19mmc: fsl_esdhc: fix probe issue without CONFIG_BLK enabledYangbo Lu
u-boot is trying to make CONFIG_BLK as a hard requirement for DM_MMC. But now it's still not. config BLK bool "Support block devices" depends on DM default y if DM_MMC When fsl_esdhc driver was reworked for DM_MMC support, DM_MMC without CONFIG_BLK enabled wasn't considered. This patch is to fix probe issue without CONFIG_BLK enabled.

U-Boot code currently only applies this restriction to HS200 mode, extend this to HS400 mode as well. Currently U-Boot code not support accessing boot partition in HS200/400 mode.

2019-05-21mmc: tmio: sdhi: HS400 manual adjustmentMarek Vasut
Since Gen3 SDHI has an internal DS signal AC-spec violation in HS400 mode, CRC-error may occur in read command in HS400 mode. This phoenomenon occurs at low/high temperature. To fix this, after completion of HS400 tuning, enable manual calibration. However, Gen3 M3 Ver.1.2 or earlier and H3 1.x does not support HS400. These SoC forcibly use HS200 mode by SoC attribute. The DT adjustment of the tuning parameters is not supported until the DT property names become clear.

2019-05-20Revert "mmc: fsl_esdhc: fix sd/mmc ddr mode clock setting issue"Lukasz Majewski
This reverts commit 72a89e0da5ac6a4ab929b15a2b656f04f50767f6, which causes the imx53 HSC to hang as the eMMC is not working properly anymore. The exact error message: MMC write: dev # 0, block # 2, count 927 ... mmc write failed 0 blocks written: ERROR imx53 is not using the DDR mode. Debugging of pre_div and div generation showed that those values are generated in a way, which is not matching the ones from working setup. As the original patch was performing code refactoring, let's revert this change, so all imx53 boards would work again. Signed-off-by: Lukasz Majewski <lukma@denx.de>

2019-04-29mmc: dw_mmc: Round up descriptor end to nearest multiple of cacheline sizeMarek Vasut
The driver currently calculates the end address of cache flush operation for the DMA descriptors by adding cacheline size to the start address of the last DMA descriptor. This is not safe, as the cacheline size may be, in some unlikely cases, smaller than the DMA descriptor size. Replace the addition with roundup() applied on the end address of the last DMA descriptor to round it up to the nearest cacheline size multiple.

To avoid this freeze: -The driver must define a DTIME on all r1b response type. -DTIME of SDMMC must be defined for alls stop transmission (for read and write request) even if MMC_RSP_BUSY is not set. -If busy timeout occur, an abort request must be sent to reinitialize the DPSM.

2019-03-29mmc: correct the HS400 initialization processBOUGH CHEN
After the commit b9a2a0e2e9c0 ("mmc: Add support for downgrading HS200/HS400 to HS mode"), it add a parameter in mmc_set_card_speed() which indicates that the HS200/HS400 to HS downgrade is happening. During the HS400 initialization, first select to HS200, and config the related clock rate, then downgrade to HS mode. So here also need to config the downgrade value to be true for two reasons. First, make sure in the function mmc_set_card_speed(), after switch to HS mode, first config the clock rate, then read the EXT_CSD, avoid receiving data of EXT_CSD in HS mode at 200MHz. Second, after issue the MMC_CMD_SWITCH command, it need to wait a bit then switch bus properties. Test on i.MX8QM MEK board, some Micron eMMC will stuck in transfer mode in this case, and USDHC will never get data transfer complete status, cause the uboot hang.

Errata i929 in certain OMAP5/DRA7XX/AM57XX silicon revisions (SPRZ426D - November 2014 - Revised February 2018 [1]) mentions unexpected tuning pattern errors. A small failure band may be present in the tuning range which may be missed by the current algorithm. Furthermore, the failure bands vary with temperature leading to different optimum tuning values for different temperatures. As suggested in the related Application Report (SPRACA9B - October 2017 - Revised July 2018 [2]), tuning should be done in two stages. In stage 1, assign the optimum ratio in the maximum pass window for the current temperature. In stage 2, if the chosen value is close to the small failure band, move away from it in the appropriate direction.
