From bc6bbd6be85973359e89f53e3bfbba2a3549da09 Mon Sep 17 00:00:00 2001 From: Poonam Aggrwal Date: Thu, 7 Jul 2011 20:36:47 +0530 Subject: fsl_ifc: Add the workaround for erratum IFC A-003399(enabled on P1010) Issue: Address masking doesn't work properly. When sum of the base address, defined by BA, and memory bank size, defined by AM, exceeds 4GB (0xffff_ffff) then AMASKn[AM] doesn't mask CSPRn[BA] bits. Impact: This will impact booting when we are reprogramming CSPR0(BA) and AMASK0(AMASK) while executing from NOR Flash. Workaround: Re-programming of CSPR(BA) and AMASK is done while not executing from NOR Flash. The code which programs the BA and AMASK is executed from L2-SRAM.
