[PATCH v8 18/37] drivers/cpu: Add generic armv8 cpu driver

[PATCH v8 18/37] drivers/cpu: Add generic armv8 cpu driver

[Patrick Rudolph]

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.

[PATCH v8 19/37] arm: gic-v3-its: Rename objects

[Patrick Rudolph]

The code accesses the gic-v3 node, but not the gic-v3-its node,
thus rename the objects to clarify which node it operates on.

The following commit will make use of the gic-v3-its node for real.

Aren't gicv3 at least #interrupt-cells = 3; to distinguish PPI / SPI?

Don't you have to distinguish PPI and SPIs here? You'll use
args->args[0] as PPI vs SPI and args[1] is either 1:1 (PPI) or offset
by 32 for SPIs or am I misunderstanding something?

Yes, you are right. I missed that since qemu SBSA uses #interrupt-cells=1.

[PATCH v8 23/37] drivers/arm: Implement acpi_fill_madt

[Patrick Rudolph]

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.

[PATCH v8 27/37] arm: mach-bcm283x: Bring in some header files from tianocore

[Patrick Rudolph]

From: Simon Glass <sjg@chromium.org>

These header files presumably duplicate things already in the U-Boot
devicetree. For now, bring them in to get the ASL code and ACPI table
code to compile.

[PATCH v8 31/37] armv8: cpu: Enable ACPI parking protocol

[Patrick Rudolph]

Update the generic entry point code to support the ACPI parking protocol.
The ACPI parking protocol can be used when PSCI is not available to bring
up secondary CPU cores.

When enabled secondary CPUs will enter U-Boot proper and spin in their own
4KiB reserved memory page, which also acts as mailbox with the OS to
release the CPU.

TEST: Boots all CPUs on qemu-system-aarch64 -machine raspi4b
