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 stable DT ABI.

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. Signed-off-by: Janne Grunau <j@jannau.net> Acked-by: Mark Kettenis <kettenis@openbsd.org>
Ernest Van Hoecke <ernestvanhoecke@gmail.com> says: This patch series migrates the Aquila AM69 to OF_UPSTREAM to receive automatic device tree updates. It also adds remoteproc firmware pre-loading to the environment. Link: https://lore.kernel.org/r/20260417-elb-6911-aquila69-ofupstr-v1-0-400d93db3747@toradex.com

Add a devicetree overlay and UFS variants of the Genio 520 and Genio 720 EVK devicetree targets. There are dip switches and jumpers on the EVK that disconnect the eMMC and connect the UFS instead. The overlay adjusts the devicetree for this.

Add a basic .dts file for MediaTek Genio 520/720 EVKs. This will suffice until an upstream devicetree is available from Linux. These boards are virtually identical (other than some camera capabilities) so share mostly the same devicetree.
