Subject: [PATCH 2/2] ARM: BCM5301X: Fix NAND ECC parameters for D-Link DIR-885L
Date: Mon, 6 Jun 2016 09:43:50 +0200 [thread overview]
Message-ID: <1465199036-24366-2-git-send-email-zajec5@gmail.com> (raw)
In-Reply-To: <1465199036-24366-1-git-send-email-zajec5@gmail.com>
This device uses BCH-1 instead of BCH-8. This fixes ECC errors and makes
NAND usable with brcmnand.

As suggested recently, the new file uses BSD-compatible license. I was
considering BSD [23]-clause license and Hauke said he likes ISC which is
even simpler, so I picked this one.
