From 9f074e67f5a2131336ff1838f2a82e0c2e15d33c Mon Sep 17 00:00:00 2001 From: Prabhakar Kushwaha Date: Wed, 29 Oct 2014 22:33:09 +0530 Subject: [PATCH] powerpc/mpc85xx:Put errata number for T104x NAND boot issue When device is configured to load RCW from NAND flash IFC_A[16:31] are driven low after RCW loading. Hence Devices connected on IFC_CS[1:7] and using IFC_A[16:31] lines are not accessible. Workaround is already in-place. Put the errata number to adhere errata handling framework.
