This is due to the fact that the board uses a shared MDIO bus for
both ethernet controllers, but FEC_MXC_SHARE_MDIO is not enabled.
This results in a double free in fecmxc_remove(). To fix this
enable CONFIG_DM_MDIO so the shared MDIO is correctly detected
from the devicetree.

No watchdog was enabled for STM32MP13 platform. Add the required flags to
support it. As done for STM32MP15 (in SCMI config) and STM32MP2x, we use
the Arm SMC watchdog. The required nodes were already present in Linux
imported DT files (stm32mp13.dtsi & stm32mp135f-dk.dts).
To enable this SMC watchdog on other platforms based on STM32MP13, check
that both the following flags are enabled in the dedicated config file:
CONFIG_WDT=y
CONFIG_WDT_ARM_SMC=y
And that there is a node in Linux board DT that enables the feature, as
it is done in stm32mp135f-dk.dts:
&arm_wdt {

Add support for building U-Boot for Cortex-M33 RSIP core in Renesas
R-Car Gen5 R8A78000 X5H SoC. The main goal is to start U-Boot on the
Cortex-M33 RSIP core, which initializes the hardware and then starts
the Cortex-M33 SCP and Cortex-A720 cores which run the SCP firmware
and applications software respectively. The SCP is responsible for
platform resource management, and is used to start other CPU cores.
The Cortex-M33 build contains its own r8a78000_ironhide_cm33_defconfig
which configures the build for aarch32 instruction set compatible with
the ARMv8M core. The build also uses -cm33 DT and -u-boot.dtsi which
are derived from their non-CM33 counterparts, and add CM33 specifics.
The arch/arm/mach-renesas/u-boot-rsip.lds is derived from generic
arch/arm/cpu/u-boot.lds with adjustments to cater to the RSIP core,
those are entrypoint before vectors, __data_start/__data_end symbols
for data-only relocation, and placement of BSS into read-write SRAM
area.

Enable OF_UPSTREAM to use upstream Linux kernel DT source as a base
for U-Boot control DT. Retain currently present parts of the DT which
are not yet part of upstream Linux kernel DT in -u-boot.dtsi files
until they get replaced by upstream equivalents. Add renesas/ prefix
to the DEFAULT_DEVICE_TREE as part of the switch.
Unused i2c2..i2c8 nodes have been removed, and will become available
once upstream Linux kernel DT adds those nodes.
The DRAM_RSV_SIZE has been updated to cover first 518 MiB of DRAM,
which are reserved for firmware and other use.
Note that all DT parts in -u-boot.dtsi are not considered stable DT
bindings and may change before they land in Linux kernel and become

Janne Grunau <j@jannau.net> says:
The Linux device trees for Apple silicon devices cover now most of the
hardware as u-boot's internal device trees for M1 devices. Linux has in
addition device trees M2 and M1 and M2 Pro/Max/Ultra devices which were
never added in u-boot.
The most common use case for u-boot on Apple silicon devices does not
use DTBs from u-boot but passes runtime modified device trees from an
earlier boot loader (m1n1).
This change regresses support for the SPI on M1 and M1 Pro/Max notebooks
as SPI keyboard support is not in upstream Linux. This regression is in
my opinion acceptable due to the limited use of u-boot's DTBs for these
targets.
Link: https://lore.kernel.org/r/20260507-apple-dt-upstream-v2-0-35181f2b0509@jannau.net
The device tree on Apple silicon devices is passed from a previous
bootloader stage. The bootloader fills in dynamic information so
u-boot can not use its own device tree.
As documented in doc/board/apple/m1.rst it is possible to build boot
bundles (bootloader + device tree + gzipped u-boot binary). These are
useful for testing.
Instead of using u-boot's own device trees for M1 (t8103) devices use
upstream device trees from dts/upstream/src/arm64/apple. The u-boot
device trees have not seen updates since 2022. The upstream linux device
trees have feature parity for the M1 devices. In addition linux has
device trees for M1 Pro/Max/Ultra, M2 and M2 Pro/Max/Ultra devices.
Keep t8103-j274 as default device tree to avoid further updates.

Two recent additions to the mainline device tree allow us
to switch away from the local U-Boot copy:
* Board/embedded controller (traverse,ten64-controller)
is now in the mainline device tree.
* USB Hub (USB5744) connections were also added to
the mainline device tree but not in U-Boot.
The LS1088A and Ten64 device trees in U-Boot were actually
'synced' to mainline some time ago, so the content
(except for the changes mentioned above) is identical.

With correct POSIX handling, unquoted empty variables can turn the
expression like
test -n ${fdtfile}
into
test -n
The POSIX handling for single argument `test` evaluates it as true,
so the fallback initialization will be skipped unexpectedly.
Quoting variable expansions in `test` expressions will always result in
correct behavior for empty and non-empty values.
This change was triggered by
commit 8b0619579b ("cmd: test: fix handling of single-argument form of test")
The aim is to have a less fragile codebase that is not dependent on a
quirk of the shell implementation.
Use quoted variable expansions in `test` expressions throughout.

CONFIG_DRAM_SUNXI_TPR6 is the only DRAM config parameter that has a
non-zero default value. Since we need to provide a value for all the
other parameters anyway, avoiding TPR6 makes no real difference.
To make matters worse, TPR6 is a compound value covering multiple DRAM
types, but also spans over three SoCs, which makes it hard to find one
good default value.
Drop the default from Kconfig, and put some explicit values in the
defconfigs for the few boards that were relying on the default so far.
The value is taken from one BSP, only the lower byte matters anyway for
those boards, all using DDR3 DRAM.
