From 5de8ca95506a5f15bfbfdd2ca9babd282a882d1f Mon Sep 17 00:00:00 2001 From: Robert Date: Tue, 13 Mar 2018 14:29:00 +0100 Subject: arch-riscv: enable rudimentary fs simulation These changes enable a simple binary to be simulated in full system mode. Additionally, a new fault was implemented. It is executed once the CPU is initialized. This fault clears all interrupts and sets the pc to a reset vector.
