From 32c741d07f7fdb1974eb07420fc143d479bfe19f Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Wed, 17 Sep 2014 15:45:39 +0200 Subject: [PATCH] ARM: mvebu: switch the Armada 370 RD board to internal registers at 0xf1000000 Recent bootloader versions from Marvell that have DT support and various other new features remap the internal registers at 0xf1000000. We have already done this change for most of the development boards from Marvell, and this commit does this change for the Marvell Armada 370 RD board.
