riscv: Add initial support for 32bit boards
* Adding separate targets for 32bit and 64bit qemu * Using the riscv64 toolchain for 32bit builds requires setting -m elf32lriscv * rv32/rv64 is currently configured with ARCH_RISCV_RV32/RV64 and not per stage. This should probably be changed later. TEST=Boots to "Payload not loaded." on 32bit qemu using the following commands: util/riscv/make-spike-elf.sh build/coreboot.rom build/coreboot.elf qemu-system-riscv32 -M virt -m 1024M -nographic -kernel build/coreboot.elf Change-Id: I35e59b459d1770df10b51fe9e77dcc474d7c75a0 Signed-off-by: Philipp Hug <philipp@hug.cx> Reviewed-on: https://review.coreboot.org/c/31253 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: ron minnich <rminnich@gmail.com>
