3 	tristate "Enable UBI - Unsorted block images"
6 	  UBI is a software layer above MTD layer which admits use of LVM-like
15 	int "UBI wear-leveling threshold"
21 	  of UBI devices. When this threshold is exceeded, UBI starts performing
36 	  This option specifies the maximum bad physical eraseblocks UBI
47 	  To put it differently, if this value is 20, UBI will try to reserve
50 	  partition UBI attaches. This means that if you have, say, a NAND
52 	  MTD partitions of the same size, UBI will reserve 40 eraseblocks when
55 	  This option can be overridden by the "mtd=" UBI module parameter or
61 	bool "UBI Fastmap (Experimental feature)"
67 	   Fastmap is a mechanism which allows attaching an UBI device
72 	   attaching by scanning takes long. UBI will not automatically install
73 	   a fastmap on old images, but you can set the UBI module parameter
75 	   images are still usable with UBI implementations without

85 	   devices on top of UBI volumes: for each UBI volumes an MTD device is
86 	   created, and all I/O to this MTD device is redirected to the UBI

92 	bool "Read-only block devices on top of UBI volumes"
96 	   This option enables read-only UBI block devices support. UBI block
97 	   devices will be layered on top of UBI volumes, which means that the
98 	   UBI driver will transparently handle things like bad eraseblocks and
99 	   bit-flips. You can put any block-oriented file system on top of UBI
103 	   When selected, this feature will be built in the UBI driver.
108 	bool "Fault injection capability of UBI device"
112 	   This option enables fault-injection support for UBI devices for
118 	tristate "UBI virtual NVMEM"
122 	   This option enabled an additional driver exposing UBI volumes as NVMEM
