From 8c77ef85405dd319f0469d007630b548afb2d401 Mon Sep 17 00:00:00 2001 From: Yuan Yao Date: Wed, 8 Jun 2016 18:24:54 +0800 Subject: [PATCH] armv8: ls2080aqds: disable IFC NOR & QIXIS when QSPI enable When QSPI is enabled, NOR flash and QIXIS can't be accessed through IFC due to pin mux. Enable I2C QIXIS access and I2C early init to read the sysclk and ddrclk.
