+Capsule Generation through binman
+*********************************
+
+Support has also been added to generate capsules during u-boot build
+through binman. This requires the platform's DTB to be populated with
+the capsule entry nodes for binman. The capsules then can be generated
+by specifying the capsule parameters either through a config file, or
+by specifying them as properties in the capsule entry node.
