2019-07-13mmc: Register only the first MMC device on MMC_TINYEzequiel Garcia
When MMC_TINY is enabled, support for only one MMC device is provided. Boards that register more than one device, will just write over mmc_static keeping only the last one registered. This commit prevents this, keeping only the first MMC device created. A debug warning message is added, if nothing else, as a hint/documentation for developers.

2019-06-23mmc: split fsl_esdhc driver for i.MXYangbo Lu
The fsl_esdhc driver was for Freescale eSDHC on MPC83XX/MPC85XX initially. The later QoriQ series PowerPC processors (which were evolutions of MPC83XX/MPC85XX), QorIQ series ARM processors, and i.MX series processors were using this driver for their eSDHCs too. For the two series processors, the eSDHCs are becoming more and more different. We should have split it into two drivers, like them (sdhci-of-esdhc.c/sdhci-esdhc-imx.c) in linux kernel. This patch is just to create a fsl_esdhc_imx driver which is a copy of fsl_esdhc driver for i.MX processors. We will convert i.MX processors to use fsl_esdhc_imx, and clean up the two drivers separately in the future patches.

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.

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.

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.
