Since the orignial file didn't have a SPDX tag, don't add one to this new file - leave the original GPL copyright header untouched. > diff --git a/include/hw/misc/riscv_cmgcr.h b/include/hw/misc/riscv_cmgcr.h > new file mode 100644 > index 0000000000..d7145a51af > --- /dev/null > +++ b/include/hw/misc/riscv_cmgcr.h > @@ -0,0 +1,50 @@ > +/* > + * This file is subject to the terms and conditions of the GNU General Public > + * License.
