Some MMC peripherals require specific power cycle sequence, where some
registers need to be written between the regulator is turned off and then
back on. This is the case for the MMC IP embedded in STM32MP1 SoC.
In STM32MP157 reference manual [1], the power cycle sequence is:
1. Reset the SDMMC with the RCC.SDMMCxRST register bit. This will reset
the SDMMC to the reset state and the CPSM and DPSM to the Idle state.
2. Disable the Vcc power to the card.
3. Set the SDMMC in power-cycle state. This will make that the
SDMMC_D[7:0], SDMMC_CMD and SDMMC_CK are driven low, to prevent the card
from being supplied through the signal lines.
4. After minimum 1ms enable the Vcc power to the card.
5. After the power ramp period set the SDMMC to the power-off state for
minimum 1ms. The SDMMC_D[7:0], SDMMC_CMD and SDMMC_CK are set to
drive “1”.
6. After the 1ms delay set the SDMMC to power-on state in which the
SDMMC_CK clock will be enabled.
7. After 74 SDMMC_CK cycles the first command can be sent to the card.
The step 3. cannot be handled by the current framework implementation.
A new callback (host_power_cycle) is created, and called in
mmc_power_cycle(), after mmc_power_off().
The incorrect power cycle sequence has shown some boot failures on
STM32MP1 with some SD-cards, especially on cold boots when the input
frequency is low (<= 25MHz).
Those failures are no more seen with this correct power cycle sequence.

In SPL, all the available mmc devices gets initialized during boot.
This might not work in cases where clocks are not available for
certain mmc devices(other than boot device) and the support for
enabling device might not be ready.
Texas Instruments' K3 J721E device having a central system controller
(dmsc) is one such example falling in this category. Below is the
sequence for the failing scenario:
- ROM comes up in SD mode and loads SPL by just initialing SD card.
- SPL loads dmsc firmware from SD Card.
Since ROM has enabled SD, SPL need not enable the SD, just need
to re initialize the card. But SPL is trying to initialize other MMC
instances which are in disabled state. Since dmsc firmware is not yet
available, devices cannot be enabled. So in SPL, initialize only the
mmc device that is needed.

Merge tag 'u-boot-atmel-2020.01-a' of https://gitlab.denx.de/u-boot/custodians/u-boot-atmel
First set of u-boot-atmel features and fixes for 2020.01 cycle
The feature set includes support for two new boards from Microchip AT91:
The sama5d27_wlsom1_ek , an evaluation kit which includes the SAMA5D2
SOC packaged in a 256 MB LPDDR2 SIP, on a SOM including wireless, which
is placed on evaluation kit with sd-card, ethernet, LCD, Camera sensor,
QSPI, etc
The sam9x60ek, an evaluation kit for the new SoC based on ARM926j , the
SAM9X60 . The evaluation kit includes NAND flash, QSPI, Ethernet, Audio,
Camera sensor connector, etc.
The full support for sam9x60ek will come at a later time. There are
still missing bits regarding the clock support and power management
controller.

U-Boot binary has grown in such a way that it goes beyond the reserved
area for the environment variables.
Running "saveenv" causes U-Boot to hang because of this overlap.
Fix this problem by increasing the CONFIG_ENV_OFFSET size.
Also, in order to prevent this same problem in the future, use
CONFIG_BOARD_SIZE_LIMIT, which will detect the overlap in build-time.
CONFIG_BOARD_SIZE_LIMIT does not accept math expressions, so declare

Previously the SPL size on all iMX6 platforms was restricted to 68KB
because the OCRAM size on iMX6SL/DL parts is only 128KB. However, the
other iMX6 variants have 256KB of OCRAM. Add an option
CONFIG_MX6_OCRAM_256KB which allows using the full size on boards which
don't need to support the SL/DL variants. This allows for an SPL size of
196KB, which makes it much easier to use configurations such as SPL with
driver model and FDT control.
