From b10f1c836c4e8c2372d14953a17aa5b9744eb55c Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Fri, 11 Jul 2014 13:00:37 +0200 Subject: [PATCH] ARM: pxa: Move UNCACHED_PHYS_0 mapping from generic.c to pxa2[57]x.c The UNCACHED_PHYS_0 mapping is only needed on PXA25x and PXA27x platforms. Move it to pxa25x.c and pxa27x.c to avoid wasting vmalloc space on PXA3xx.
