PS4: 
dying here: 
745		if (scratch->fw_rw_offset == 0 ||
746		    (scratch->fw_rw_offset & (scratch->fw_rw_offset - 1)) != 0) {
747			sbi_printf("%s: fw_rw_offset is not a power of 2 (0x%lx)\n",
748				   __func__, scratch->fw_rw_offset);
749			return SBI_EINVAL;

because
(gdb) print/x scratch->fw_rw_offset
$11 = 0x60000
(gdb) print/x (scratch->fw_rw_offset & (scratch->fw_rw_offset - 1))
$12 = 0x40000

fragile code.
