The AX650 Demo board is based on the AX650 SoC and provides the hardware platform used to validate this series. This series adds the initial upstream support required to build and boot the Linux kernel on the AX650 Demo board. The initial platform support includes: - Axera AX650 SoC and AX650 Demo devicetree bindings - ARCH_AXERA arm64 platform selection - arm64 defconfig support - Cortex-A55 CPUs and PSCI - GIC-400 interrupt controller - ARMv8 architectural timer - Cortex-A55 PMU - UART console - 8 GiB system memory - Axera ARM64 SoC maintainer information The patches are organized as follows: - Patch 1/6: Add the Axera vendor prefix. - Patch 2/6: Add devicetree bindings for the AX650 SoC and AX650 Demo board. - Patch 3/6: Add the ARCH_AXERA arm64 platform option. - Patch 4/6: Enable ARCH_AXERA in the arm64 defconfig. - Patch 5/6: Add the initial devicetree description for the AX650 SoC and AX650 Demo board. - Patch 6/6: Add Axera ARM64 SoC entries to MAINTAINERS. The series is intentionally limited to the minimum platform support required to boot the board with a serial console. Additional peripherals will be added in subsequent patches. The platform was tested on an AX650 Demo board using the vendor boot chain to load the kernel and device tree. A kernel with an embedded initramfs successfully reached an interactive shell on the serial console, and all 8 CPUs were brought online.
