[PATCH V3 0/8] Add basic ACPI support for risc-v virt |

This series adds the basic ACPI support for the RISC-V virt machine.
Currently only RINTC interrupt controller specification is approved by the
UEFI forum. External interrupt controller support in ACPI is in progress.
The basic infrastructure changes are mostly leveraged from ARM.
This adds support for RINTC and RHCT tables as specified in below ECR links
which are approved by UEFI forum.
RINTC - https://drive.google.com/file/d/1R6k4MshhN3WTT-hwqAquu5nX6xSEqK2l/view
RHCT - https://drive.google.com/file/d/1nP3nFiH4jkPMp6COOxP6123DCZKR-tia/view
These changes are also available @
https://github.com/vlsunil/qemu/tree/acpi_b1_us_review_V3
Changes since V2:
1) Squashed commits and updated commit message as per feedback from
Daniel.
2) Addressed comments from Drew.
3) Updated tags.
Changes since V1:
1) Addressed comments from Bin Meng.
2) Made acpi switch default AUTO similar to other architectures.
3) Re-based and added RB and ACKs.
The series is tested using SBI HVC console and initrd.
Test instructions:
1) Build Qemu with ACPI support (this series)
2) Build EDK2 as per instructions in
https://github.com/vlsunil/riscv-uefi-edk2-docs/wiki/RISC-V-Qemu-Virt-support
3) Build Linux with ACPI support using below branch
https://github.com/vlsunil/linux/commits/acpi_b1_us_review_ipi17_V2
after enabling SBI HVC and SBI earlycon options.
CONFIG_RISCV_SBI_V01=y
CONFIG_SERIAL_EARLYCON_RISCV_SBI=y
CONFIG_HVC_RISCV_SBI=y
4) Build buildroot.
Run with below command.
qemu-system-riscv64 -nographic \
-drive
file=Build/RiscVVirtQemu/RELEASE_GCC5/FV/RISCV_VIRT.fd,if=pflash,format=raw,unit=1
\
-machine virt -smp 16 -m 2G \
-kernel arch/riscv/boot/Image \
-initrd buildroot/output/images/rootfs.cpio \
-append "root=/dev/ram ro console=hvc0 earlycon=sbi"
