+All versions of the KB1200 microcontrollers from ENE include internal
+flash. The eneispif flash driver supports the KB1200 family of devices. The driver
+automatically recognizes the specific version's flash parameters and
+autoconfigures itself. The flash bank starts at address 0x60000000. An optional additional
+parameter sets the address of eneispif controller, with the default address is 0x50101000.
+
+@example
+
+flash bank $_FLASHNAME eneispif 0x60000000 0 0 0 $_TARGETNAME \
+           0x50101000
