4a1a593d17 pci: pci_mvebu: Move setup for BAR[0] where other BARs are setup
Function mvebu_pcie_setup_wins() sets up all other BARs, so move setup of
BAR[0] to this function to have common code at one place.

In the past, commit 193a1e9f19 ("pci: pci_mvebu: set BAR0 after memory
space is set") moved setup of BAR[0] to another location, due to ath10k
not working in kernel, but the reason why was unknown, but it seems to
work now, and we think the issue then was cause by the PCIe Root Port
presenting itself as a Memory Controller and therefore U-Boot's code
have overwritten the BAR. Since the driver now ignores any write
operations to PCIe Root Port BARs, this should not be an issue anymore.

ccea46c05b i2c: mvtwsi: Swab the register address if its size is > 1
Testing on Armada XP with an EEPROM using register address with size
of 2 has shown, that the register address bytes are sent to the I2C
EEPROM in the incorrect order. This patch swabs the address bytes so
that the correct address is transferred to the I2C device.

BTW: This worked without any issues before migrating Armada XP to
DM I2C.

d8063dc373 efi: Add a media/block driver for EFI block devices
Add a block driver which handles read/write for EFI block devices. This
driver actually already exists ('efi_block') but is not really suitable
for use as a real U-Boot driver:

- The operations do not provide a udevice
- The code is designed for running as part of EFI loader, so uses
    EFI_PRINT() and EFI_CALL().
- The bind method probes the device, which is not permitted
- It uses 'EFI' as its parent device

The new driver is more 'normal', just requiring its platform data be set
up in advance.

8777033722 net: eth-phy: Handle gpio_request_by_name() return value
The gpio_request_by_name() returns zero in case of success, however the
conditional return value check in gpio_request_by_name() checks only for
(ret != -ENOENT) and if the condition is true, returns ret outright.

This leads to a situation where successful gpio_request_by_name() return
leads to immediate successful eth_phy_of_to_plat() return as well, and
to skipped parsing of "reset-assert-us" and "reset-deassert-us", so the
PHY driver operates with valid reset GPIO, but with assert/deassert times
set to default, which is 0, instead of the values from DT. This breaks
PHY reset.

Fix this by checking if return value is non-zero and then for this one
single allowed non-zero return value, -ENOENT.

8c1a6957b1 drivers: net: Soft reset felix switch core
It turns out that in custom designs if the system is reset
multiple times in conjunction with a slight increase in external
temperature, the felix  switch starts to behave in a strange way:
packets are no longer received on the ENECT interface connected
to the L2switch internal port (the TX side of internal port stops working
or the packets do not reach there. It is not very clear where
the packets remain blocked. None of the counters points to a disruption
in the L2switch)
The issue is not reproducible on NXP reference designs.

It was observed that by adding the switch core reset, the problem
goes aways, even if intensive testing in temperature chambers
is applied.

The current patch performs soft reset on the switch core to ensure proper
operation of the L2switch.

af13df7014 dm: add debug message when failed to select the default pinctrl
Add a message on probe in driver model core when the default
pinctrl selection failed.

This message is displayed only when the pinctrl API is
implemented, i.e. when result is not ENOSYS.

This also introduces CONFIG_SYS_BR0_PRELIM_BOOL as not all platforms

to platforms that had not been previously migrated.

Since the commit f42045b2e7 ("stm32mp15: replace CONFIG_TFABOOT when
it is possible") the function stm32mp1_ddr_setup is always called so the
__maybe_unused can be removed.

d72e7bbe7c ram: stm32mp1: compute DDR size from DDRCTL registers
Compute the DDR size from DDR controller register (mstr and addrmap)
in U-Boot proper as the DDR information are useful only for SPL
but not for U-Boot proper, for example with TFABOOT.

This patch simplify U-Boot DT when several DDR size are supported
and support of next SOC in STM32MP family.

b3c29dc9e5 stm32mp1: ram: remove tuning support
Remove the DDR interactive command tuning, as the support of a predefined
DDR PHY tuning is removed for STM32MP1 driver in SPL and in TF-A
and the result of this tuning will be never used.

Moreover this SW tuning procedure can failed on some hardware
configuration (to many BIST errors and no convergence); it will be no
more supported in the next delivery of the DDR utilities included in
the CubeMX tool of STMicroelectronics.

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.
