arch-riscv: Fix reset function and style
In addition to fixing some style issues with resetting, this patch fixes what happens on reset. The RISC-V privileged ISA reference manual says that, on reset: 1. Privilege mode is set to M 2. mstatus.mie <- 0; mstatus.mprv <- 0 3. PC <- reset vector 4. mcause <- reset cause (0 if there is no distinguishing causes) 5. Everything else is undefined Because of 5, everything else will be left alone Change-Id: I81bdf7a88b08874e3c3d5fc6c7f3ca2d796496b8 Reviewed-on: https://gem5-review.googlesource.com/c/14376 Reviewed-by: Jason Lowe-Power <jason@lowepower.com> Maintainer: Jason Lowe-Power <jason@lowepower.com>
