From d5ed8c5727f6985505ceb6e8640528e7e08e9670 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 11 Sep 2015 20:17:47 +0900 Subject: ARM: uniphier: change the external bus address mapping In UniPhier SoCs before ProXstream2 and PH1-LD6b, two address spaces 0x00000000 - 0x0fffffff 0x40000000 - 0x4fffffff are both mapped to the external bus (also called system bus), so either was OK. In the newest two SoCs, the former (0x00000000 - 0x0fffffff) is assigned for the serial NOR interface. Going forward, use the latter for the external bus.
