In case the DHSOM is in suspend state and either reset button is pushed
or IWDG2 triggers a watchdog reset, then DRAM initialization could fail
as follows:
"
RAM: DDR3L 32bits 2x4Gb 533MHz
DDR invalid size : 0x4, expected 0x40000000
DRAM init failed: -22
### ERROR ### Please RESET the board ###
"
Avoid this failure by not keeping any Buck regulators enabled during reset,
let the SoC and DRAMs power cycle fully. Since the change which keeps Buck3
VDD enabled during reset is ST specific, move this addition to ST specific
SPL board initialization so that it wouldn't affect the DHSOM .

When a push-button is released and PA13/PA14 are defined as input (high-Z)
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

Check whether user has explicitly defined the mmc device to use

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

This patch allows to override this selection for the support of customer

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.
