Changes in v2: - rebase on u-boot/master - drop the patch "riscv: Pass correct exception code to _exit_trap()" - drop the patch "riscv: Refactor handle_trap() a little for future extension" - drop the patch "riscv: Allow U-Boot to run on hart 0 only", and leave the SMP support to Lukas's future patch series
