[PATCH v2 0/7] risc-v: add ACPI support on QEMU

[Heinrich Schuchardt]

QEMU 8.1.2 can create ACPI tables for the RISC-V architecture.
Allow passing them through to the operating system.
Provide a new defconfig that enables this.

This series depends on

https://lore.kernel.org/u-boot/20231109172302.54324-1-heinrich.schuchardt@canonical.com/

v2:
	provide a new Kconfig symbol CONFIG_QFW_ACPI
