Pointing over at x86 where we have dts files, yes, please remove the word "still" and perhaps otherwise reword a few things. U-Boot is happy to pass along ACPI and so forth to the OS, but will continue using device tree internally.
Based on the existing work done by Simon Glass this series adds support for booting aarch64 devices using ACPI only. As first target QEMU SBSA support is added, which relies on ACPI only to boot an OS. As secondary target the Raspberry Pi4 was used, which is broadly available and allows easy testing of the proposed solution. The series is split into ACPI cleanups and code movements, adding Arm specific ACPI tables and finally SoC and mainboard related changes to boot a Linux on the QEMU SBSA and RPi4. Currently only the mandatory ACPI tables are supported, allowing to boot into Linux without errors. The QEMU SBSA support is feature complete and provides the same functionality as the EDK2 implementation. The changes were tested on real hardware as well on QEMU v9.0: qemu-system-aarch64 -machine sbsa-ref -nographic -cpu cortex-a57 \ -pflash secure-world.rom \ -pflash unsecure-world.rom qemu-system-aarch64 -machine raspi4b -kernel u-boot.bin -cpu cortex-a72 \ -smp 4 -m 2G -drive file=raspbian.img,format=raw,index=0 \ -dtb bcm2711-rpi-4-b.dtb -nographic Please note that the current implementation still requires a DTB to be provided to U-Boot and that the DTB is used within U-Boot to load drivers, to disable/enable certain hardware blocks in ACPI. The DTB is not passed to the OS when using the bootefi cmd. Tested against FWTS V24.03.00. Known issues: - The QEMU rpi4 support is currently limited as it doesn't emulate PCI, USB or ethernet devices! - The SMP bringup doesn't work on real hardware, but works in QEMU. - PCI on RPI4 isn't working on real hardware since the pcie_brcmstb Linux kernel module doesn't support ACPI yet.
