From 51100bdc067706624f0ffe285e63a6099336e11a Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 20 Aug 2013 15:47:38 -0600 Subject: ARM: tegra: remove common.c common.c was create to contain code shared across the various Tegra board files. There is now only one board file, tegra.c. So, move the code there. One exception is the PMC reboot routine, which moves to pmc.c, and now takes advantage of the 'standard' tegra_pmc_readl/writel functions.

00:00:00 2001 From: Stephen Warren Date: Tue, 20 Aug 2013 16:19:15 -0600 Subject: ARM: tegra: move resume vector define to irammap.h irammap.h's purpose is to define the layout/usage of IRAM. As such, TEGRA_IRAM_CODE_AREA should have been added there rather than iomap.h. Move the define, and rename it something more descriptive.

Most of this information comes from device tree now, and hence can be deleted. Entries are kept for various system peripherals that low-level code (such as initial boot, system suspend/resume, debug) still requires.
