Subject: [PATCH 3/4] mtd: rawnand: cadence: change bad block marker size
Date: Mon, 10 Feb 2020 10:55:27 +0100 [thread overview]
Message-ID: <1581328530-29966-3-git-send-email-piotrs@cadence.com> (raw)
In-Reply-To: <1581328530-29966-1-git-send-email-piotrs@cadence.com>
Increase bad block marker size from one byte to two bytes.
Bad block marker is handled by skip bytes feature of HPNFC.
Controller excpects this value to be an even number.
