Merge patch series "This series introduces initial U-Boot support for mach-axiado AX3005 SCM3005 board, a quad-core ARM Cortex-A53 (ARMv8/ARM64) platform."

2026-06-11T13:51:13Z

Siu Ming Tong says: Patch 1 adds the device tree files: an SoC-level DTSI describing GIC-v3, Cadence/Zynq UART, a fixed reference clock, and spin-table secondary CPU boot, plus a board-level DTS setting the console to uart3 at 115200 baud with 2 GB DRAM at 0x80000000. Patch 2 adds mach-axiado to support Axiado SoC-based boards, Kconfig plumbing (AXIADO_AX3005 and TARGET_SCM3005), defconfig, board source with ft_board_setup() and a MAINTAINERS entry.

grm: axiado: Add AX3005 based SCM3005 board support

2026-06-10T20:52:25Z

Introduce mach-axiado to support Axiado SoC-based boards. This adds the platform Kconfig and build infrastructure, along with initial SCM3005 board support using the AX3005 SoC. Introduces AXIADO_AX3005, which selects ARM64, driver model, GIC-v3, and Zynq UART. TARGET_SCM3005 selects ARCH_AXIADO, allowing future SoC variants to share the platform configuration. Secondary cores use spin-table boot. ft_board_setup() corrects the cpu-release-addr in the FDT, which arch_fixup_fdt() overwrites with the post-relocation address. Add U-Boot board support for the Axiado AX3005 based targets, a quad-core ARM Cortex-A53 (ARMv8) platform. Tested-by: Siu Ming Tong Signed-off-by: Karthikeyan Mitran Signed-off-by: Siu Ming Tong

arm: dts: Switch Apple silicon devices to dts/upstream

2026-05-12T18:11:08Z

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 Acked-by: Mark Kettenis

arm: Add ARMv8-M aarch32 support

2026-04-13T23:34:02Z

Add configuration for ARMv8-M aarch32 core, which are currently Cortex-M23/M33 cores. These cores are treated similar to ARMv7-M cores, except the code has to be compiled with matching compiler -march=armv8-m.main flag . These cores have no MMU, they have MPU, which is currently not configured. Unlike ARMv7-M, these cores have 512 interrupt vectors. While the SYS_ARM_ARCH should be set to 8, it is set to 7 because all of the initialization code is built from arch/arm/cpu/armv7m and not armv8. Furthermore, CONFIG_ARM64 must be disabled, although DTs for devices using these cores do come from arch/arm64/boot/dts. To avoid excess duplication in Makefiles, introduce one new Kconfig symbol, CPU_V7M_V8M. The CPU_V7M_V8M cover both ARMv7-M and ARMv8-M cores. Signed-off-by: Marek Vasut Acked-by: Udit Kumar

arm: k3: Kconfig: Enable fTPM and RPMB support

2026-03-10T18:35:18Z

Enable firmware TPM (fTPM) support via OP-TEE for K3 platforms with MMC hardware. This provides TPM 2.0 functionality through Microsoft's fTPM Trusted Application running in OP-TEE secure world, using eMMC RPMB as persistent storage. fTPM support in U-Boot provides the foundation for measured boot and disk encryption use cases. The ARM64 condition ensures these apply only to A53/A72 cores and the MMC condition ensures fTPM is enabled only on platforms with eMMC hardware support.

board: nxp: Rename board directory from board/freescale to board/nxp

2026-01-28T06:26:50Z

This patch renames the board directory from board/freescale to board/nxp because NXP now provides Board Support Packages (BSPs) and tools for the former Freescale i.MX and other i.MX products. All relevant references have been updated accordingly. This change does not affect functionality. Signed-off-by: Alice Guo Reviewed-by: Fabio Estevam
