This series primarily enables external interrupt controllers (AIA and PLIC) in ACPI tables for RISC-V virt platform. It also updates RHCT with CMO and MMU related information.
Below ECRs for these changes are approved by ASWG and will be available in next ACPI spec release. 1) MADT (AIA) - https://drive.google.com/file/d/1oMGPyOD58JaPgMl1pKasT-VKsIKia7zR/view?usp=sharing 2) RHCT - https://drive.google.com/file/d/1sKbOa8m1UZw1JkquZYe3F1zQBN1xXsaf/view?usp=sharing First two patches in this series are to migrate a couple of functions from ARM architecture to common code so that RISC-V doesn't need to duplicate the same. The patch set is based on Alistair's riscv-to-apply.next branch. These changes are also available in riscv_acpi_b2_v5 branch at: https://github.com/vlsunil/qemu/ Changes since v4: 1) Updated copyright for new files as per SPDX format suggested by Drew. 2) Updated RINTC patch to avoid code duplication as suggested by Drew. 3) Moved mmu offset below cmo in MMU patch as suggested by Drew. 4) Updated tags. Changes since v3: 1) Addressed comments from Daniel and Drew. 2) Added a new patch in microvm to use common function for virtio in DSDT. 3) Rebased to latest riscv-to-apply.next branch and added tags. Changes since v2: 1) Rebased to latest riscv-to-apply.next branch which needed changing ext_icboz to ext_zicboz in CMO patch. 2) Fixed node type in MMU node. 3) Added latest tags. Changes since v1: 1) As per Igor's suggestion, migrated fw_cfg and virtio creation functions to device specific file instead of generic aml-build.c. Since ACPI is optional, new files are created and enabled for build only when CONFIG_ACPI is enabled. 2) As per Igor's suggestion, properties are added to the GPEX PCI host to indicate MMIO ranges. The platform fw can initialize these to appropriate values and the DSDT generator can fetch the information from the host bus itself. This makes the code generic instead of machine specific. 3) Added PLIC patch from Haibo. 4) Rebased to latest riscv-to-apply.next and added RB tags as appropriate.
