        bool "support MMC boot partitions"
+       help
+         Provide access to the 'boot partitions' of devices of type 'MMC'.
+         These so called 'hardware partitions' act like an independent memory
+         device and thus, need special handling.
+
+         Note: only 'MMC' have 'boot partitions'. So, if you don't use an
+         'MMC' device, you don't need this support.
