riscv, qemu_fw_cfg: Add support for RISC-V architecture
Qemu fw_cfg support was missing for RISC-V, which made it hard to do proper vmcore dumps from qemu. Add the missing RISC-V arch-defines. You can now do vmcore dumps from qemu. Add "-device vmcoreinfo" to the qemu command-line. From the qemu monitor: (qemu) dump-guest-memory vmcore The vmcore can now be used, e.g., with the "crash" utility. Acked-by: "Michael S. Tsirkin" <mst@redhat.com> Acked-by: Alistair Francis <alistair.francis@wdc.com> Tested-by: Clément Léger <cleger@rivosinc.com> Signed-off-by: Björn Töpel <bjorn@rivosinc.com> Message-Id: <20231012102852.234442-1-bjorn@kernel.org> Signed-off-by: Michael S.
