treewide: Staticize and constify acpi ops

2026-06-29T21:29:44Z

Set the acpi_ops structure as static const where applicable. The The structure is not accessible from outside of drivers and is not going to be modified at runtime. The structure may be unused in a couple of drivers depending on their configuration, mark those sites with __maybe_unused . Signed-off-by: Marek Vasut Reviewed-by: Simon Glass

drivers/arm: Implement acpi_fill_madt

2024-10-27T23:24:13Z

Fill the MADT table in the GIC driver and armv8 CPU driver to drop SoC specific code. While the GIC only needs devicetree data, the CPU driver needs additional information stored in the cpu_plat struct. While on it update the only board making use of the existing drivers and writing ACPI MADT in mainboard code. TEST: Booted on QEMU sbsa-ref using GICV3 driver model generated MADT. Booted on QEMU raspb4 using GICV2 driver model generated MADT. Signed-off-by: Patrick Rudolph Reviewed-by: Simon Glass Cc: Simon Glass

drivers/cpu: Add generic armv8 cpu driver

2024-10-27T23:24:13Z

Add a generic driver that binds to armv8 CPU nodes. The generic driver allows - to enumerate CPUs present in a system, even when no other driver binds it - generates ACPI SSDT code for each CPU - Fill the ACPI MADT table (implemented in a follow up patch) The newly introduced code could also be reused on other CPU drivers that are compatible with armv8. TEST: Booted on QEMU sbsa and verify the driver binds to CPU nodes. Confirmed with FWTS that all ACPI processor devices are present.
