+         This option provides support for runtime services provided
+         by UEFI firmware (such as non-volatile variables, realtime
+          clock, and platform reset). A UEFI stub is also provided to
+         allow the kernel to be booted as an EFI application. This
+         is only useful on systems that have UEFI firmware.
