A bunch of cleanups for arch/arm/mach-tegra, mostly just deleting
stale code.
Stephen Warren (7):
ARM: tegra: remove common.c
ARM: tegra: delete stale header content
ARM: tegra: delete gpio-names.h
ARM: tegra: move resume vector define to irammap.h
ARM: tegra: remove much of iomap.h
ARM: tegra: remove tegra_chip_uid()
ARM: tegra: make tegra_init_fuse() __init

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.

gpio-names.h defines IDs for GPIOs. This information now comes from
device tree, so delete this stale header. The one remaining use-case is
board-paz00.c's wifi_rfkill device. Isolate the knowledge of those GPIO
IDs into that file. Let's hope the values stay valid:-)

gpio-names.h defines IDs for GPIOs. This information now comes from
device tree, so delete this stale header. The one remaining use-case is
board-paz00.c's wifi_rfkill device. Isolate the knowledge of those GPIO
IDs into that file. Let's hope the values stay valid:-)

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.

From: Stephen Warren <swarren-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>
iomap.h defines the base address of Tegra peripherals. 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.
Removing the values removes the temptation for someone to use them.

This function is no longer used. It's also only accurate for Tegra20.

NOTE: Depends on "crypto: tegra: use kernel entropy instead of ad-hoc",
which is in the crypto tree; not sure for which release...

This function is no longer used. It's also only accurate for Tegra20.

I've applied this series, excluding patch 6 which I expect to go through
the crypto tree along with the patch it depends on, to Tegra's
for-3.13/cleanup branch.
