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.
