From b6a4226c14001b0aa20b11c69190cb89d2237d3d Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Mon, 29 Oct 2012 20:50:21 -0600 Subject: ARM: OMAP2+: common: remove mach-omap2/common.c globals and map_common_io code Get rid of the mach-omap2/common.c globals by moving the global initialization for IP block addresses that must occur early into mach-omap2/io.c. In the process, remove the *_map_common_io*() and SoC-specific *set_globals* functions.

These functions need to be able to save the reboot reason into the scratchpad RAM. This implies a dependency on both the PRM and SCM IP blocks, so they've been moved into their own file. This will eventually call functions in the PRM and SCM drivers, once those are created. Vaibhav Hiremath identified an unused prototype in the first version of this patch - now removed. Tony Lindgren noted a compile problem with some RMK Kconfigs; resolved in this patch.
