riscv: fix compatibility with Linux toolchain
Previously, RISC-V in gem5 only supported RISC-V's Newlib toolchain (riscv64-unknown-elf-*) due to incorrect assumptions made in the initial setup of the user stack in SE mode. This patch fixes that by referring to the RISC-V proxy kernel code (https://github.com/riscv/riscv-pk) and setting up the stack according to how it does it. Now binaries compiled using the Linux toolchain (riscv64-unknown-linux-gnu-*) will run as well. [Update for recent changes to MemState to add accessors and mutators to get its members.] Change-Id: I6d2c486df7688efe3df54273e9aa0fd686851285 Reviewed-on: https://gem5-review.googlesource.com/2305 Maintainer: Alec Roelke <ar4jc@virginia.edu> Reviewed-by: Brandon Potter <Brandon.Potter@amd.com> Reviewed-by: Jason Lowe-Power <jason@lowepower.com>
