From b8fb878aa2485fd41502295f0ff5362a67c8ba68 Mon Sep 17 00:00:00 2001 From: Anup Patel Date: Tue, 31 Aug 2021 16:36:01 +0530 Subject: hw/intc: Upgrade the SiFive CLINT implementation to RISC-V ACLINT The RISC-V ACLINT is more modular and backward compatible with original SiFive CLINT so instead of duplicating the original SiFive CLINT implementation we upgrade the current SiFive CLINT implementation to RISC-V ACLINT implementation.
