Subject: [PATCH] ARM: dts: imx6ull: fix ubi mount failed on MYS-6ULX-IOT board
Date: Tue,  9 Mar 2021 14:15:19 +0800	[thread overview]
Message-ID: <1615270520-16951-1-git-send-email-dillon.minfei@gmail.com> (raw)

From: dillon min <dillon.minfei@gmail.com>

This patch intend to fix ubi filesystem mount failed on MYS-6ULX-IOT board,
from Micron MT29F2G08ABAEAWP's datasheets, we need to choose 4-bit ECC.

Table 18: Error Management Details

Description					Requirement

Minimum number of valid blocks (NVB) per LUN	2008
Total available blocks per LUN			2048
First spare area location			x8: byte 2048 x16: word 1024
Bad-block mark					x8: 00h x16: 0000h
Minimum required ECC				4-bit ECC per 528 bytes
Minimum ECC with internal ECC enabled		4-bit ECC per 516 bytes (user data) + 8
						bytes (parity data)
Minimum required ECC for block 0 if PROGRAM/
ERASE cycles are less than 1000			1-bit ECC per 528 bytes
