└─>Micro Memory MM5415 Battery Backed RAM support
In linux kernel since version 2.6.20 (release Date: 2007-02-04)
Saying Y here will include support for the MM5415 family of
battery backed (Non-volatile) RAM cards.
<http://www.umem.com/>
The cards appear as block devices that can be partitioned into
as many as 15 partitions.
To compile this driver as a module, choose M here: the
module will be called umem.
The umem driver has not yet been allocated a MAJOR number, so
one is chosen dynamically.
