bcfb365375 mmc: fsl_esdhc: Fix PIO timeout
The following error has been observed on i.MX25 with a high-speed SDSC
card:
    Data Write Failed in PIO Mode.

It was caused by the timeout set on PRSSTAT.BWEN, which was triggered
because this bit takes 15 ms to be set after writing the first block to
DATPORT with this card. Without this timeout, all the blocks are
properly written.

This timeout was implemented by decrementing a variable, so it was
depending on the CPU frequency. Fix this issue by setting this timeout
to a long enough absolute duration (500 ms).

9b643e312d treewide: replace with error() with pr_err()
U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

  # define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux.  (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// <smpl>
@@@@
-error
+pr_err
 (...)
// </smpl>

3d3108d459 mmc: sdhci-cadence: set timing mode register depending on frequency
The MMC framework in U-Boot does not support a systematic API for
timing switch like mmc_set_timing() in Linux.

U-Boot just provides a hook to change the clock frequency via
mmc_set_clock().  It is up to drivers if additional register
settings are needed.

This driver needs to set a correct timing mode into a register when
it migrates to a different speed mode.  Only increasing clock frequency
could result in setup/hold timing violation.

The timing mode should be decided by checking MMC_TIMING_* like
drivers/mmc/host/sdhci-cadence.c in Linux, but "timing" is not
supported by U-Boot for now.  Just use mmc->clock to decide the
timing mode.

b312c590bc mmc: Add MMC support for stm32h7 Socs
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.

ead3697d7e mmc: sunxi: fix legacy MMC initialisation
The driver-model rework changed, among other things, the way the private
data were moved around. It now uses the private field in the struct mmc.

However, the mmc_create argument was changed in the process to always pass
the array we used to have to store our private structures.

The basically means that all the MMC driver instances will now have the
private data of the first instance, which obviously doesn't work very well.

Pass the proper pointer to mmc_create.

Almost all of the newer Allwinner SoCs have a new operating mode for the

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.

Add support for it through a Kconfig option.

The command handling in this driver is awful, esp. because the driver

might not be needed as it turns out the uniphier-sd.c driver is in much
