+.BI "\-c [" "comment" "]"
+Specifies a comment to be added when signing. This is typically a useful
+message which describes how the image was signed or some other useful
+information.

.TP
.BI "\-D [" "dtc options" "]"
Provide special options to the device tree compiler that is used to
verification. Typically the file here is the device tree binary used by
CONFIG_OF_CONTROL in U-Boot.

+.BI "\-r
+Specifies that keys used to sign the FIT are required. This means that they
+must be verified for the image to boot. Without this option, the verification
