22 + ---help---
23 + MyLoader is a bootloader which allows the user to define partitions
24 + in flash devices, by putting a table in the second erase block
25 + on the device, similar to a partition table. This table gives the
26 + offsets and lengths of the user defined partitions.
27 +
28 + If you need code which can detect and parse these tables, and
29 + register MTD 'partitions' corresponding to each image detected,
30 + enable this option.
31 +
32 + You will still need the parsing functions to be called by the driver
33 + for your particular device. It won't happen automatically.
