REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4076
Add support for RISC-V qemu virt machine. Most of the changes are migrated from edk2-platforms repo and added qemu specific libraries under OvmfPkg. The series has passed CI tests (https://github.com/tianocore/edk2/pull/4023) These changes are available at: https://github.com/vlsunil/edk2/tree/RiscV64QemuVirt_V8 The series can be tested as per instructions @ https://github.com/vlsunil/riscv-uefi-edk2-docs/wiki/RISC-V-Qemu-Virt-support Changes since V7: 1) Addressed feedbacks from Mike and Ray. 2) Added Anrdrei as another reviewer for RiscVVirt 3) Rebased 4) Added RB and ACK tags Changes since V6: 1) Took inspiration from IntelTdx and added all RISC-V qemu related libraries and modules in OvmfPkg/RiscVVirt instead of directly under OvmfPkg/Library. Hoping for quicker review since now it shouldn't affect the existing OvmfPkg libraries/modules. 2) Dropped migration of NvVarStoreFormattedLib for now to avoid MdeModulePkg changes. Currently RISC-V Qemu doesn't support separate variable flash. So, it can be taken as a separate activity in future when required. 3) Rebased and new CI test request passed Changes since V5: 1) Avoided editing the existing INF files (as per feedback from Ray Ni). This reduced several refactor patches. 2) Moved to PEI less design (as per suggestion from Andrei Warkentin) 3) Added PciCpuIO2Dxe driver in OvmfPkg. 4) Removed APRIORI requirement in DSC/FDF infrastructure files. Now they are very similar to ArmVirtQemu. 5) Addressed Heinrich's feedback. 6) Rebased and added ack tags Changes since V4: 1) Rebased and added ACKs 2) Dropped few patches related to VirtNorFlashDxe since they are already taken care by Ard. Changes since V3: 1) Addressed Abner's comments 2) Changed folder name from Ia32_X64 to Ia32X64 as per latest guidelines. 2) Rebased Changes since V2: 1) Fixed issues detected by CI 2) Added an extra patch to fix up the consumers of NvVarStoreFormattedLib Changes since V1: 1) Added couple of patches from Ard to optimize the NorFlashDxe in Ovmf. Note: There will be a separate patch series in future to update existing consumers of NorFlashDxe driver. 2) Migrated NvVarStoreFormattedLib from EmbeddedPkg to MdeModulePkg 3) Created Null instance of the NorFlashPlatformLib library class 4) Moved NorFlashPlatformLib.h from ArmPlatformPkg Cc: Abner Chang <abner.ch...@amd.com> Cc: Daniel Schaefer <g...@danielschaefer.me> Cc: Michael D Kinney
