	  life-cycle less than 10000, the threshold should be lessened (e.g.,

	  to 128 or 256, although it does not have to be power of 2).

	help

	  If the MTD device admits of bad eraseblocks (e.g. NAND flash), UBI

	  reserves some amount of physical eraseblocks to handle new bad

	  eraseblocks. When a physical eraseblock becomes bad, UBI uses these

	  reserved physical eraseblocks to relocate the bad one. This

	  configuration option specifies how many physical eraseblocks will be

	  reserved for bad eraseblock handling (percents of total number of

	  good physical eraseblocks on this MTD partition). If the underlying

	  flash does not admit of bad eraseblocks (e.g. NOR flash), this value

	  is ignored and nothing is reserved. Leave the default value if

	  unsure.

config MTD_UBI_BEB_LIMIT

	int "Percentage of maximum expected bad eraseblocks"

	default 2
