Currently only RINTC interrupt controller specification is approved by the UEFI forum. External interrupt controller support in ACPI is in progress. 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_V5 Changes since V4: 1) Used possible_cpus to create cpu topology in DSDT, MADT and RHCT as per Igor's feedback. 2) Moved MAINTAINER entries below ACPI/SMBIOS entry as per Drew's feedback Changes since V3: 1) Added back acpi_align_size() wrapper as per Drew's feedback 2) Updated RB tags 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.
