Although most flash chips have an erase size too large to be useful
|
||
|
as block devices, it is possible to use MTD devices which are based
|
||
|
on RAM chips in this manner. This block device is a user of MTD
|
||
|
devices performing that function.
|
||
|
|
||
|
At the moment, it is also required for the Journalling Flash File
|
||
|
System(s) to obtain a handle on the MTD device when it's mounted
|
||
|
(although JFFS and JFFS2 don't actually use any of the functionality
|
||
|
of the mtdblock device).
|
||
|
|
||
|
Later, it may be extended to perform read/erase/modify/write cycles
|
||
|
on flash chips to emulate a smaller block size. Needless to say,
|
||
|
this is very unsafe, but could be useful for file systems which are
|
||
|
almost never written to.
|
||
|
|
||
|
You do not need this option for use with the DiskOnChip devices. For
|
||
|
those, enable NFTL support (CONFIG_NFTL) instead.

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

'normal' form of partitioning used on a block device.
