4369c6a050 board: st: factorize STM32MP FWU multi-bank support
Factorize FWU multi-bank support code common to STM32MP1 and

560d8f3270 board: st: stm32mp15: support dynamic A/B bank bootup
Following commit 4300f9f4c5 ("board: st: stm32mp25: support dynamic
A/B bank bootup"), this patch enables automatic detection of the active
A/B bank on STM32MP15 platforms by retrieving partition GUIDs from FWU
metadata.

This ensures the system correctly identifies the bootable partitions
even in multi-bank scenarios, falling back to a standard bootable flag
scan if the UUIDs are missing.

To enable A/B bank bootup on STM32MP15 boards, add the following Kconfig
options to the  stm32mp15[_basic]_defconfig:

 CONFIG_FWU_MULTI_BANK_UPDATE=y
 CONFIG_FWU_MDATA=y
 CONFIG_FWU_NUM_BANKS=2
 CONFIG_FWU_NUM_IMAGES_PER_BANK=3
 CONFIG_CMD_FWU_METADATA=y
 CONFIG_FWU_MDATA_V2=y

ecde6614bc board: stm32pm1: Fix board_check_usb_power()
Depending of plugged power source (computer, wall charger, ...) it can
happen that we got the following message:

"****************************************************"
"*      USB TYPE-C charger not compliant with       *"
"*                   specification                  *"
"****************************************************"
"                                                    "
"### ERROR ### Please RESET the board ###            "

This issue has been detected on STM32MP135f-DK board.

It's due to max_uV and min_uV value are initialized at beginning of
board_check_usb_power() and can then be used for the 2 iteration of
adc_measurement().
max_uV/min_uV values issued of the first adc_measurement() iteration
are used as input of the second adc_measurement() iteration, which
can lead to incoherent pair of min_uV/max_uV values.

To ensure that adc_measurement() returns coherent value for max_uV and
min_uV, initialize max_uV and min_uV at each loop start.

This reverts commit d37641c61b.

Restore support for environment storage in EXT4 filesystem on eMMC boot.
The previous cleanup incorrectly removed this fallback option which is
needed for boards that store their environment in an EXT4 partition.

This configuration is OS-specific rather than board-dependent and should
remain as it is configurable via menuconfig. Even if it is not described
in ST defconfigs people may have enabled it in their defconfig.

backup register. Add a function to read the boot index value from the

the LED should not be active as the circuit is open but a small current
leak through PCB or push-button close the circuit and allows a small LED
bias giving erroneous level voltage.

So it is recommended to activate an internal pull-up in order to clearly
fix the voltage at PA13/PA14 when button is released and to wait
a short delay before to read the GPIO value only when the pull-up is

2214d5e54c stm32mp1: remove the board_check_usb_power function when ADC is not activated
Simplify the code of the function board_check_usb_power
based in CONFIG_ADC and adc_measurement; the function is removed by the
linker when the CONFIG_ADC is not activated.

9f97193616 board: stm32mp1: use CONFIG_SYS_MMC_ENV_DEV when available
Check whether user has explicitly defined the mmc device to use
in mmc_get_env_dev() with CONFIG_SYS_MMC_ENV_DEV.

On STMicroelectronics boards the used mmc device for environment is
the instance of boot device provided by the ROM code; the mmc instance
is configured by alias in device tree. The used partition is defined in
device tree with u-boot,mmc-env-partition = "ssbl".

This patch allows to override this selection for the support of customer
boards without alias; for example when SDMMC1 is not used and ENV in
mmc0=SDMMC2, user can force the value: CONFIG_SYS_MMC_ENV_DEV = 0.

On STMicroelectronics boards, the current behavior is kept with
CONFIG_SYS_MMC_ENV_DEV = -1.

401d1c4f5d common: Drop asm/global_data.h from common header
Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

42082bc61b board: stm32pm1: update USB-C power detection algorithm on DK boards
USB-C power supply which are Power Delivery compliant (USB-PD) are able
to provide different voltage/current (for example 5V/3A 9V/3A 12V/2.25A...)

In this case, the power supply need to negotiate the voltage/current to
use with the device using CC1/CC2 USB-C signals.

If this negotiation occurs during ADC measurement (done also on CC1/CC2
USB-C signals) some ADC acquisition can be corrupted which cause wrong
power supply current detection.

To avoid this, the power supply current detection algorithm is updated
as following:
  - perform an ADC measurement, if a 3A current is detected, continue the
    boot process.
  - else, wait 20ms (max tPDDebounce duration) to ensure that USB-PD
    negotiation is done and perform another ADC measurement.

65e25bea59 dm: Rename DM_GET_DRIVER() to DM_DRIVER_GET()
In the spirit of using the same base name for all of these related macros,
rename this to have the operation at the end. This is not widely used so
the impact is fairly small.
