From 89ece6f76f089bc415fc4b8c78f7dbe74113380c Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Thu, 3 Sep 2020 18:40:12 +0800 Subject: hw/riscv: Move sifive_e_prci model to hw/misc This is an effort to clean up the hw/riscv directory. Ideally it should only contain the RISC-V SoC / machine codes plus generic codes. Let's move sifive_e_prci model to hw/misc directory.
