e84ee40b0b configs: stm32mp15: deactivate the CONFIG_STM32_IPCC
The IPCC mailbox is only used for communication with M4 firmware but
it is not used in the stm32 remoteproc driver; it was planed but the
support of this mailbox in remoteproc for STM32MP15x is dropped.

So the associated drivers and config CONFIG_STM32_IPCC can be
deactivated to reduce the U-Boot size; the CONFIG_DM_MAILBOX can be
also deactivated as the mailbox UCLASS is no more used.

9819fe345c stm32mp1: ram: remove the support of calibration result
The support of a predefined DDR PHY tuning result is removed for
STM32MP1 driver because it is not needed at the supported frequency
when built-in calibration is executed.

The calibration parameters were provided in the device tree by the
optional node "st,phy-cal", activated in ddr helper file by the
compilation flag DDR_PHY_CAL_SKIP and filled with values generated
by the CubeMX DDR utilities.

This patch
- updates the binding file to remove "st,phy-cal" support
- updates the device trees and remove the associated defines
- simplifies the STM32MP1 DDR driver and remove the support of
  the optional parameter "st,phy-cal"

After this patch, the built-in calibration is always executed
and the calibration registers are moved in the phy dynamic part;
that allows manual tests.

Add support for testing whether bus voltage level translator is present
and operational. This is useful on systems where the bus voltage level
translator is optional, as the translator can be auto-detected by the
driver and the feedback clock functionality can be disabled if it is
not present.

The translator test sets CMD high to avoid interfering with a card, and
then verifies whether signal set on CK is detected on CKIN. If the signal
is detected, translator is present, otherwise the CKIN feedback clock are
disabled.

c3de051c41 tis: fix tpm_tis_remove()
tpm_tis_remove() leads to calling tpm_tis_ready() with the IO region
unmapped and chip->locality == -1 (locality released). This leads to a
crash in mmio_write_bytes().

The patch implements these changes:

tpm_tis_remove(): Unmap the IO region after calling tpm_tis_cleanup().

tpm_tis_cleanup(): Request locality before IO output and releasing
locality.

c0d9bb0b4a efi_loader: Extend PCR's for firmware measurements
Firmwares before U-Boot may be capable of doing tpm measurements
and passing them to U-Boot in the form of eventlog. However there
may be scenarios where the firmwares don't have TPM driver and
are not capable of extending the measurements in the PCRs.
Based on TCG spec, if previous firnware has extended PCR's, PCR0
would not be 0. So, read the PCR0 to determine if the PCR's need
to be extended as eventlog is parsed or not.

The current tpm2_pcr_read is hardcoded using SHA256. Make the
actual command to TPM configurable to use wider range of algorithms.
The current command line is kept as is i.e limited to SHA-256 only.

34287efdaf efi_loader: Add check for event log passed from firmware
Platforms may have support to measure their initial firmware components
and pass the event log to u-boot. The event log address can be passed
in property tpm_event_log_addr and tpm_event_log_size of the tpm node.
Platforms may choose their own specific mechanism to do so. A weak
function is added to check if even log has been passed to u-boot
from earlier firmware components. If available, the eventlog is parsed
to check for its correctness and further event logs are appended to the
passed log.

5db5815e99 serial: a37xx: Reset whole UART when changing parent clock from TBG to XTAL
Sometimes UART stops transmitting characters after UART clock is changed
back to XTAL. In this state UART fifo is always full. Kernel during early
boot wants to print output on UART and is waiting for non-empty UART fifo.
Which leads to CPU hangup without any (debug) output on UART.

Marvell Armada 3700 Functional Specifications says that for programming
fractional divisor registers it is required to disable UART, enable
loopback mode, reset fifos, program registers, disable loopback mode,
release reset of fifos and enable UART.

But these steps do not fix above mentioned issue that UART hangup. Also
gating UART clock does not help. And even resetting UART state machines do
not help.

Experiments showed that UART fifo is unblocked after board is being reset
(during board reset UART HW transmit UART fifo even CPU is not executing
kernel/bootloader anymore).

And another experiments showed that same workaround can be achieved also
by external reset of UART HW (without need to reset board).

So do not implement any of "Marvell recommended" steps from Functional
Specifications as they do not work. And rather prior changing parent clock
back to XTAL, do external reset of UART HW. This operation also resets all
UART registers, so basically it also sets UART clock to default, which is
XTAL. It is unknown why UART hangups and enters such broken state.
