From 6dd937e8f634dd8de67185d887643ab7f4ec15b9 Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Fri, 23 Aug 2013 09:34:42 +0100 Subject: ARM: ux500: Delete U8500 UIB support when booting with ATAGs It's time to remove all ATAG support from ux500 and rely solely on Device Tree booting. This patch is part of that endeavour.
