From 199b75f58a0ffc2ad0871eb4853ca425c78b4893 Mon Sep 17 00:00:00 2001 From: Philipp Hug Date: Thu, 13 Sep 2018 18:11:56 +0200 Subject: arch/riscv: provide a monotonic timer The RISC-V Privileged Architecture specification defines the Machine Time Registers (mtime and mtimecmp) in section 3.1.15. Makes it possible to use the generic udelay. The timer is enabled using RISCV_USE_ARCH_TIMER for the lowrisc, sifive and ucb soc.
