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.

Add GPIO driver for the Renesas RCar SoCs . The driver currently supports
only the RCar Gen3 R8A7795 and R8A7796 SoCs, but is easily extensible for
the other RCar SoCs as well.
This driver is meant to replace the pinmux part of SH_GPIO_PFC driver.

When EHCD and xHCD are enabled at the same time, USB storage device
driver will fail to read/write from/to the storage device attached
to the xHCI interface, due to its transfer blocks exceeds the xHCD
driver limitation.
With driver model, we have an API to get the controller's maximum
transfer size and we can use that to determine the storage driver's
capability of read/write.
Note: the non-DM version driver is still broken with xHCD and the
intent here is not to fix the non-DM one, since the xHCD itself is
already broken in places like 3.0 hub support, etc.

This adds a new memeber max_xfer_blk in struct us_data to record

xHCD allocates one segment which includes 64 TRBs for each endpoint
and the last TRB in this segment is configured as a link TRB to form
a TRB ring. Each TRB can transfer up to 64K bytes, however data
buffers referenced by transfer TRBs shall not span 64KB boundaries.
Hence the maximum number of TRBs we can use in one transfer is 62.

The Linux kernel driver sets the number of event segments and entries
to 1 , while the initial import of the xhci code set that values to 3
for reasons unknown. While most controllers are fine with more event
segments with more entries, there are standard-conformant controllers
(ie. Renesas RCar xHCI) which only support 1 event segment.
Set the number of event segments and event entries back to 1 to allow
such controllers to work with U-Boot xHCI stack. Note that the Renesas
controller correctly indicates ERST Max = 1 in HCSPARAMS2[7:4] .

The content of Bank Address Register (BAR) is volatile. It is cleared
after power cycle or reset command (RESET F0h).
Some memories (like e.g. s25fl256s) use it to access memory larger than
0x1000000 (16 MiB).
The problem shows up when one:
1. Reads/writes/erases memory > 16 MiB
2. Calls "reset" u-boot command (which is not causing BAR to be cleared)
In the above scenario, the SoC ROM sends 0x000000 address to read SPL.
Unfortunately, the BA24 bit is still set and hence it receives content
from 0x1000000 (16 MiB) memory address.
As a result the SoC aborts and we hang. Only power cycle can take the
SoC out of this state.
How to reproduce/test:
sf probe; sf erase 0x1200000 0x800000; reset
sf probe; sf erase 0x1200000 0x800000; sf write 0x11000000 0x1200000 0x800000; reset
sf probe; sf read 0x11000000 0x1200000 0x800000; reset

we introduced these configs, the plan was to remove the debug version
at some point. But now it seems better to keep the full-blown version
