Subject: [PATCH 3/3] mtd: brcmnand: respect ECC algorithm set by NAND subsystem
Date: Fri, 22 Apr 2016 13:23:15 +0200	[thread overview]
Message-ID: <1461324197-1333-3-git-send-email-zajec5@gmail.com> (raw)
In-Reply-To: <1461324197-1333-1-git-send-email-zajec5@gmail.com>

It's more reliable than guessing based on ECC strength. It allows using
NAND on devices with BCH-1 (e.g. D-Link DIR-885L).
