From 56449d20e937e807e4fc35fa3e5a38f7636e7046 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Fri, 6 Sep 2019 09:19:58 -0700 Subject: [PATCH] riscv: sifive: Rename sifive_prci.{c, h} to sifive_e_prci.{c, h} Current SiFive PRCI model only works with sifive_e machine, as it only emulates registers or PRCI block in the FE310 SoC. Rename the file name to make it clear that it is for sifive_e. This also prefix "sifive_e"/"SIFIVE_E" for all macros, variables and functions.
