[PULL 32/71] hw/riscv/shakti_c: Check CPU type in machine_run_board_init()

Posted by Philippe Mathieu-Daudé 10 months, 3 weeks ago

From: Gavin Shan <gshan@redhat.com>

Set mc->valid_cpu_types so that the user specified CPU type can
be validated in machine_run_board_init(). We needn't to do it
by ourselves.
