From 477c894ff475be9886bd936fa8eeef7bfe862161 Mon Sep 17 00:00:00 2001 From: Ebony Zhu Date: Fri, 25 Apr 2014 18:38:44 -0500 Subject: [PATCH] board/freescale: Move CRC32 offset in NXID v1 data format According to AN3638, CRC of NXID v1 is at the end of the 256-byte I2C memory. The wrong CRC32 offset prevents Uboot from reading system information from EEPROM. No NXID v0 is being used on Freescale boards.
