ec48b6c991 arm64: versal: Add support for new Xilinx Versal ACAPs
Xilinx is introducing Versal, an adaptive compute acceleration platform
(ACAP), built on 7nm FinFET process technology. Versal ACAPs combine
Scalar Processing Engines, Adaptable Hardware Engines, and Intelligent
Engines with leading-edge memory and interfacing technologies to deliver
powerful heterogeneous acceleration for any application. The Versal AI
Core series has five devices, offering 128 to 400 AI Engines. The series
includes dual-core Arm Cortex™-A72 application processors, dual-core Arm
Cortex-R5 real-time processors, 256KB of on-chip memory with ECC, more
than 1,900 DSP engines optimized for high-precision floating point with
low latency.

The patch is adding necessary infrastructure in place without enabling
platform which is done in separate patch.

83dc42271f mmc: Retry some MMC cmds on failure
With certain SD cards like Kingston 8GB/16GB UHS card, it is seen that
MMC_CMD_ALL_SEND_CID cmd fails on first attempt, but succeeds
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
attempt, therefore retry this cmd a few times as done in kernel.

To make it clear that those are optionnal workarounds, a new Kconfig
option 'MMC_QUIRKS' is added (enabled by default).

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.

Details about that mode are sparse, and the name itself (new mode vs old

sampling of the MMC clock. One side effect is also that it divides the
parent clock rate by 2.
