Subject: [PATCH v8 5/5] mtd: nand: set max_bb_per_die and blocks_per_die for ONFI compliant chips
Date: Tue, 10 Jan 2017 13:30:21 -0600	[thread overview]
Message-ID: <1484076621-7789-6-git-send-email-zach.brown@ni.com> (raw)
In-Reply-To: <1484076621-7789-1-git-send-email-zach.brown@ni.com>

ONFI compliant chips contain the values for the max_bb_per_die and
blocks_per_die 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.
