With certain SD cards like Kingston 8GB/16GB UHS card, it is seen that

subsequently. Therefore, retry MMC_CMD_ALL_SEND_CID cmd a few time
as done in Linux kernel.
Similarly, it is seen that MMC_CMD_SET_BLOCKLEN may fail on first

This patch adds SD/MMC support for STM32H7 SoCs.

Here is an extraction of SDMMC main features, embedded in
STM32H7 SoCs.
The SD/MMC block include the following:
 _ Full compliance with MultiMediaCard System Specification
   Version 4.51. Card support for three different databus modes:
   1-bit (default), 4-bit and 8-bit.
 _ Full compatibility with previous versions of MultiMediaCards
   (backward compatibility).
 _ Full compliance with SD memory card specifications version 4.1.
   (SDR104 SDMMC_CK speed limited to maximum allowed IO speed,
    SPI mode and UHS-II mode not supported).
 _ Full compliance with SDIO card specification version 4.0.
   Card support for two different databus modes: 1-bit (default)
   and 4-bit. (SDR104 SDMMC_CK speed limited to maximum allowed IO
   speed, SPI mode and UHS-II mode not supported).
 _ Data transfer up to 208 Mbyte/s for the 8 bit mode.
   (depending maximum allowed IO speed).
 _ Data and command output enable signals to control external
   bidirectional drivers.

The current version of the SDMMC supports only one SD/SDIO/MMC card
at any one time and a stack of MMC Version 4.51 or previous.

Almost all of the newer Allwinner SoCs have a new operating mode for the
eMMC clocks that needs to be enabled in both the clock and the MMC
controller.

Details about that mode are sparse, and the name itself (new mode vs old
mode) doesn't give much details, but it seems that the it changes the
sampling of the MMC clock. One side effect is also that it divides the
parent clock rate by 2.

Add support for it through a Kconfig option.

At present if U-Boot proper uses driver model for MMC, then SPL has to
also. While this is desirable, it places a significant barrier to moving
to driver model in some cases. For example, with a space-constrained SPL
it may be necessary to enable CONFIG_SPL_OF_PLATDATA which involves
adjusting some drivers.

Add new SPL versions of the options for DM_MMC, DM_MMC_OPS and BLK. By
default these follow their non-SPL versions, but this can be changed by
boards which need it.
