From bf027ca13738b1548910351952c3fe9b63263a9a Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 29 Oct 2012 13:54:06 -0700 Subject: ARM: OMAP: Split sram.h to local headers and minimal shared header Most of the defines are specific to omap1 and omap2+, and should be in the local headers. Only minimal function prototypes need to be shared. As discussed on linux-arm-kernel, we want to avoid relative includes for the arch/arm/*omap* shared code: http://www.spinics.net/lists/linux-omap/msg80520.html So this patch re-adds a minimal plat/sram.h. The new plat/sram.h must not be included from drivers, that will break build for omap2+ CONFIG_MULTIPLATFORM. Note that this patch temporarily adds two more relative includes; Those will be removed in the following patch.
