++	---help---
++	  MyLoader is a bootloader which allows the user to define partitions
++	  in flash devices, by putting a table in the second erase block
++	  on the device, similar to a partition table. This table gives the 
++	  offsets and lengths of the user defined partitions.
++
++	  If you need code which can detect and parse these tables, and
++	  register MTD 'partitions' corresponding to each image detected,
++	  enable this option.
++
++	  You will still need the parsing functions to be called by the driver
++	  for your particular device. It won't happen automatically.
