[PATCH 0/6] RISC-V ACLINT Support

[Anup Patel]

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 in a month) can be
found at:
https://github.com/riscv/riscv-aclint/blob/main/riscv-aclint.adoc

This series adds RISC-V ACLINT support to OpenSBI and can be found in
the riscv_aclint_v1 branch at:
https://github.com/avpatel/qemu.git

To test series, we require QEMU and Linux with ACLINT support which
can be found in riscv_aclint_v1 branch at:
https://github.com/avpatel/qemu.git
https://github.com/avpatel/linux.git

Anup Patel (6):
  lib: utils/timer: Add ACLINT MTIMER library
  lib: utils/ipi: Add ACLINT MSWI library
  lib: utils: Add FDT parsing API common for both ACLINT and CLINT
  lib: utils/ipi: Add FDT based ACLINT MSWI IPI driver
  lib: utils/timer: Add FDT based ACLINT MTIMER driver
  platform: Replace CLINT library usage with ACLINT library
