Subject: [PATCH v3 5/5] mtd: nand: set bb_per_lun and blocks_per_lun for ONFI compliant chips

ONFI compliant chips contain the values for the bb_per_lun and
blocks_per_lun fields in the parameter page. When the ONFI paged is
retrieved/parsed the chip's fields are set by the corresponding fields
in the param page.
