Subject: [U-Boot] [PATCH v5 07/30] vexpress64: Add MMU tables
Date: Fri, 4 Mar 2016 01:09:51 +0100 [thread overview]
Message-ID: <1457050214-117592-8-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1457050214-117592-1-git-send-email-agraf@suse.de>
There's no good excuse for running with caches disabled on AArch64,
so let's just move the vexpress64 target to enable the MMU and run
with caches on.
Signed-off-by: Alexander Graf <agraf@suse.de>

v1 -> v2:
- Move tables to .c file
