 #                  PL011 UART. @verbose-static is mutually exclusive
 #                  with @verbose-dynamic.
 #
+# @host-uefi-vars: The firmware expects the host to provide an uefi
+#                  variable store.  qemu supports that via
+#                  "uefi-vars-sysbus" (aarch64, riscv64, loongarch64)
+#                  or "uefi-vars-x64" (x86_64) devices.  The firmware
+#                  will not use flash for nvram.  When loading the
+#                  firmware into flash the 'stateless' setup should be
+#                  used.  It is recommened to load the firmware into
+#                  memory though.

 # Since: 3.0
