From bf4b558eba920a38f91beb5ee62a8ce2628c92f7 Mon Sep 17 00:00:00 2001 From: Mark Salter Date: Mon, 7 Apr 2014 15:39:52 -0700 Subject: arm64: add early_ioremap support Add support for early IO or memory mappings which are needed before the normal ioremap() is usable. This also adds fixmap support for permanent fixed mappings such as that used by the earlyprintk device register region.
