ae7020b435 mmc: fsl_esdhc: convert to CONFIG_FSL_ESDHC_VS33_NOT_SUPPORT
For eSDHC, power supply is through peripheral circuit.
Some eSDHC versions have value 0 of the bit but that
does not reflect the truth. 3.3V is common for SD/MMC,
and is supported for all boards with eSDHC in current
u-boot. So, make 3.3V is supported in default in code.
CONFIG_FSL_ESDHC_VS33_NOT_SUPPORT can be enabled if
future board does not support 3.3V.

This is also a fix-up for one previous patch, which converted
to use IS_ENABLED() for CONFIG_SYS_FSL_MMC_HAS_CAPBLT_VS33
that is not a Kconfig option.

f9bb0baa75 mmc: octeontx_hsmmc: Add support for MIPS Octeon
Until now, the Octeontx MMC driver did only support the ARM Octeon
TX/Tx2 platforms. This patch adds support for the MIPS Octeon platform
to this driver. Here a short summary of the changes:

- Enable driver compilation for MIPS Octeon, including the MMC related
  header file
- Reorder header inclusion
- Switch to using the clk framework to get the input clock
- Remove some functions for MIPS Octeon, as some registers don't
  exist here

According to the AM654x Data Manual[1], the setup timing in lower speed
modes can only be met if the controller uses a falling edge data launch.

To ensure this, the HIGH_SPEED_ENA (HOST_CONTROL[2]) bit should be
cleared in default speed, SD high speed, MMC high speed, SDR12 and SDR25
speed modes.

Use the sdhci writeb callback to implement this condition.

c927d65873 mmc: fsl_esdhc: workaround for hardware 3.3v IO reliability issue
When eSDHC operates at 3.3v, damage can accumulate in an internal
level shifter at a higher than expected rate. The faster the interface
runs, the more damage accumulates. This issue now is found on LX2160A
eSDHC1 for only SD card.

The hardware workaround is recommended to use an on-board level shifter
that is 1.8v on SoC side and 3.3v on SD card side.

For boards without hardware workaround, this option could be enabled,
ensuring 1.8v IO voltage and disabling eSDHC if no card.
This option assumes no hotplug, and u-boot has to make all the way to
to linux to use 1.8v UHS-I speed mode if has card.
If you do not want the workaround for better user experience, of course
you can choose to not select it running eSDHC in unsafe mode.

fa33d20749 mmc: split fsl_esdhc driver for i.MX
The fsl_esdhc driver was for Freescale eSDHC on MPC83XX/MPC85XX
initially. The later QoriQ series PowerPC processors (which were
evolutions of MPC83XX/MPC85XX), QorIQ series ARM processors, and
i.MX series processors were using this driver for their eSDHCs too.

For the two series processors, the eSDHCs are becoming more and
more different. We should have split it into two drivers, like them
(sdhci-of-esdhc.c/sdhci-esdhc-imx.c) in linux kernel.

This patch is just to create a fsl_esdhc_imx driver which is a copy
of fsl_esdhc driver for i.MX processors. We will convert i.MX processors
to use fsl_esdhc_imx, and clean up the two drivers separately in the
future patches.

2acc24fc28 Kconfig: Migrate BOUNCE_BUFFER
The bounce buffer is used by a few drivers (most of the MMC drivers)
to overcome limitations in their respective DMA implementation.

This moves the configuration to Kconfig and makes it user-selectable
(even though it will be a required feature to make those drivers
work): the expected usage is for drivers depending on this to 'select'
it unconditionally from their respective Kconfig (see follow-up
patches).

This commit includes a full migration using moveconfig.py to ensure
that each commit compiles.  To ensure bisectability we update
dependencies of various drivers to now select BOUNCE_BUFFER when needed.

Allwinner A64 has new mode but doesn't have a mode switch in CCM,
and CCM_MMC_CTRL_MODE_SEL_NEW is not defined, so compilation fails
if MMC_SUNXI_HAS_NEW_MODE is enabled

Introduce new MMC_SUNXI_HAS_MODE_SWITCH option to be able to ifdef usage
of CCM_MMC_CTRL_MODE_SEL_NEW
