env: migrate static flags list to Kconfig

2026-05-25T19:44:40+00:00

Environment callbacks can already be configured from Kconfig with
CONFIG_ENV_CALLBACK_LIST_STATIC, but static environment flags still
require board headers to define CFG_ENV_FLAGS_LIST_STATIC.

Add CONFIG_ENV_FLAGS_LIST_STATIC and use it as the only board-provided
static environment flags list. Convert the remaining default-config users
from CFG_ENV_FLAGS_LIST_STATIC to defconfig settings and drop the legacy
header macro from ENV_FLAGS_LIST_STATIC.

Move the environment flags format documentation out of README and into
the developer environment documentation. Include the format in the
Kconfig help as well.

This lets boards configure writeable-list policy and type validation
from defconfig without adding a config header solely for env flags.

This preserves the behavior of default configs. Header-only cases that
were inactive in upstream defconfigs are not converted into defconfig
entries: iot2050 can add its list when enabling ENV_WRITEABLE_LIST, and
smegw01 can add mmcdev:dw support if the unlocked SYS_BOOT_LOCKED=n
configuration is needed.

arm: renesas: Add Renesas R-Car R8A78000 X5H Cortex-M33 RSIP port

2026-05-21T19:48:05+00:00

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.

arm64: renesas: Select HSCIF for DEBUG UART on R-Car Gen5 R8A78000 X5H

2026-05-21T19:48:05+00:00

The R-Car Gen5 R8A78000 X5H uses HSCIF as default serial console
interface. Select CFG_HSCIF to make debug UART code also configure
serial console interface as HSCIF instead of SCIF in case the
CONFIG_DEBUG_UART would be enabled.

arm64: dts: renesas: Switch to upstream DT on Renesas R-Car X5H R8A78000

2026-05-21T19:48:05+00:00

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
stable DT ABI.

board: nxp: lx2160a: without QIXIS, MC-ENET, PCI, LTC3882

2026-05-15T11:28:31+00:00

The shared LX2160A board file calls helpers that only exist when
their subsystem is enabled. Gate them on the matching CONFIG_*:
 - pci_init() under CONFIG_PCI.
 - fdt_fixup_mc_ddr() and fsl_rgmii_init() under CONFIG_FSL_MC_ENET.
 - qixis_*() and the QIXIS branch of checkboard() under
   CONFIG_FSL_QIXIS; cpu_name(buf) moves out so the non-QIXIS path
   still prints "Board: ".
 - EVENT_SPY_SIMPLE on init_func_vid moves inside the
   CONFIG_VOL_MONITOR_LTC3882_READ guard (was outside, dangling
   symbol when LTC3882 off).

 #if / #ifdef, not IS_ENABLED(), because the helpers are themselves
conditionally compiled.

While here, lx2160a_common.h: fix BOOT_TARGET_DEVICES_MMC
1 arg vs 2 args and gate the MMC target on CONFIG_CMD_MMC,
not CONFIG_MMC.

No functional change for NXP boards: LX2160ARDB, LX2160AQDS, or
LX2162AQDS, but mainly build clean up in order to support
other NXP lx2160a boards without those HW dependencies.

p2041rdb: use the upstream device tree

2026-05-15T11:28:30+00:00

Switch to the upstream device tree, which already includes the UART
nodes we need for the DM.

We also need to increase malloc area before relocation otherwise you'll
get the following error and the board panics:

	DRAM:  Initializing....using SPD
	alloc space exhausted ptr 414 limit 400

Merge patch series "test: Quote variables in 'test -n' expressions across boards"

2026-05-14T21:39:22+00:00

Simon Glass  says:

Several boards use 'test -n ${var}' (unquoted) in env scripts to detect
an empty variable and trigger a fallback or skip a hook. That works only
because of a U-Boot 'test' quirk where calls with argc < 3 returned
false; an empty variable made the expression 'test -n' (one operand) and
hit that path.

Commit 8b0619579b22 ("cmd: test: fix handling of single-argument form of
test") aligned 'test' with POSIX so those expressions flipped to true.
f7e7c55e53e8 ("cmd: test: add bug-compatibility special case for 'test
-n'") restored the old behaviour for the exact 'test -n' (one arg) case,
so the boards are not broken at runtime today, but the reliance on a
bug-compat path isn't great.

This series updates various boards to quote each affected variable so
the emptiness check is explicit and does not depend on the
special-case path.

Each commit carries a Fixes: tag pointing at 8b0619579b22

aristainetos2: Quote rescue_reason in rescueboot test

2026-05-14T21:39:09+00:00

The rescueboot script optionally runs a per-board rescue_reason hook
with:

    if test -n ${rescue_reason}; then run rescue_reason; fi;

The default state is "no rescue reason script", i.e. rescue_reason
unset.  The expression then expands to 'test -n' with no operand and
relies on a U-Boot 'test' quirk that treats a missing operand as
false to skip the run.

Quote the variable so an unset rescue_reason expands to 'test -n ""'
and the emptiness check is explicit.
