Subject: [PATCH] driver: mtd: ifc: Initialize SRAM for all version >= 1.0
Date: Fri, 9 Jun 2017 16:27:21 +0530	[thread overview]
Message-ID: <1497005841-7750-1-git-send-email-prabhakar.kushwaha@nxp.com> (raw)

All IFC version >= 1.0 use 28nm technology for SRAM. Here SRAM has
a requirement to initialize before any read operation performed for
avoiding ECC Error.

So update condition check to initialize SRAM for all IFC version >= 1.0.0
