[PATCH v4 0/4] QEMU RISC-V ACLINT Support |

The RISC-V Advanced Core Local Interruptor (ACLINT) is an improvement
over the SiFive CLINT but also maintains backward compatibility with
the SiFive CLINT.
Latest RISC-V ACLINT specification (will be frozen soon) can be found at:
https://github.com/riscv/riscv-aclint/blob/main/riscv-aclint.adoc
This series:
1) Replaces SiFive CLINT implementation with RISC-V ACLINT
2) Refactors RISC-V virt machine FDT generation
3) Adds optional full ACLINT support in QEMU RISC-V virt machine
This series can be found in the riscv_aclint_v4 branch at:
https://github.com/avpatel/qemu.git
Changes since v3:
- Rebased on Alistair's CPU GPIO pins v3 series
- Replaced error_report() in PATCH2 with qemu_log_mask()
Changes since v2:
- Addresed nit comments in PATCH2
- Update SSWI device emulation to match final ACLINT draft specification
Changes since v1:
- Split PATCH1 into two patches where one patch renames CLINT sources
and another patch updates the implementation
- Addressed comments from Alistar and Bin
Anup Patel (4):
hw/intc: Rename sifive_clint sources to riscv_aclint sources
hw/intc: Upgrade the SiFive CLINT implementation to RISC-V ACLINT
hw/riscv: virt: Re-factor FDT generation
hw/riscv: virt: Add optional ACLINT support to virt machine
