+
+.SH "DESCRIPTION"
+The
+\fBmkeficapsule\fP

+In this case, the update will be authenticated by verifying the signature
+before applying.

+.I raw image
+format is a single binary blob of any type of firmware.
+
+.TP
+.I FIT (Flattened Image Tree) image
+format
+is the same as used in the new \fIuImage\fP format and allows for
+multiple binary blobs in a single capsule file.
