2019-10-10mmc: add a driver callback for power-cycleYann Gautier
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. [1] https://www.st.com/resource/en/reference_manual/DM00327659.pdf Signed-off-by: Yann Gautier <yann.gautier@st.com>
2019-10-10spl: dm_mmc: Initialize only the required mmc deviceLokesh Vutla
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.

2019-10-08mx53loco: Fix U-Boot corruption after saving the environmentFabio Estevam
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 CONFIG_ENV_OFFSET with its direct value instead.

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.
