Subject: ARM: BCM5301X: Fix NAND ECC parameters for D-Link DIR-885L
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=70a0ae1c33572f012b734d4b574f38136c57f1a0;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: BCM5301X: Fix NAND ECC parameters for D-Link DIR-885L

This device uses BCH-1 instead of BCH-8. This fixes ECC errors and makes
NAND usable with brcmnand.
