From 21845825608af7fbc5513e4fbf812426df437302 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Fri, 4 Mar 2016 01:09:53 +0100 Subject: hikey: Add MMU tables The hikey runs with dcache disabled today. There really should be no reason not to use caches on AArch64, so let's add MMU definitions and enable the dcache.
