bool "MTD partitioning support"
help
If you have a device which needs to divide its flash chip(s) up
into multiple 'partitions', each of which appears to the user as
a separate MTD device, you require this option to be enabled. If
unsure, say 'Y'.
Note, however, that you don't need this option for the DiskOnChip
devices. Partitioning on NFTL 'devices' is a different - that's the
'normal' form of partitioning used on a block device.
