c9aa831ee2 Tegra: MMC: Add DT support to MMC driver for all T20 boards
tegra_mmc_init() now parses the DT info for bus width, WP/CD GPIOs, etc.
Tested on Seaboard, fully functional.

Tamonten boards (medcom-wide, plutux, and tec) use a different/new
dtsi file w/common settings.

126685ad44 Tegra: fdt: Add/enhance sdhci (mmc) nodes for all T20 DT files
Linux dts files were used for those boards that didn't already
have sdhci info populated. Tamonten has their own dtsi file with
common sdhci nodes (sourced from Linux).

6c5be646b4 Tegra: fdt: Change /include/ to #include for C preprocessor
dts Makefile has the arch & board include paths added to DTS_CPPFLAGS.
This allows the use of '#include "xyz"' in the dts/dtsi file which
helps the C preprocessor find common dtsi include files.

b7723f3f30 tegra: fdt: sort dts files
Sort nodes in dts files according the the following rules:

1) Any nodes that already exist in any /include/d file, in the order
they appear in the /include/d file.

2) Any nodes with a reg property, in order of their address.

3) Any nodes without a reg property, alphabetically by node name.

73286d8729 tegra: move common features to a common makefile
For Non-Nvidia boards to include newly added features (like emc clock
scaling) it would be necessary to add each feature to their own board
Makefile. This is because currently the top Makefile automaticly includes
these features only for Nvidia boards.

This patch adds a simple Makefile include so all new features become
available for non-Nvidia board vendors.

0cd10c7abf tegra20: rework UART GPIO handling
Rename board provided gpio_config_uart() to
gpio_early_init_uart() as it does the same thing as the equally
called function provided by the uart-switch code. This allows
to simply call this function in early board init whether or not
we are building with CONFIG_UART_SWITCH defined.

Also provide a weak symbol for this function, to avoid the
need to provide this function for boards that don't need any
fixup.

This patch supersedes the earlier posted
"tegra: convert gpio_config_uart to weak symbol".
Build tested with MAKEALL -s tegra20

150c24936b Tegra20: Move some include files to arch-tegra for sharing with Tegra30
The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h.
Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs
that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20'
'root' file.

All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK.

22d58506f5 tegra: Implement gpio_early_init() on Tamonten
The PI4 GPIO is used on Tamonten to reset carrier board peripherals.
Power sequencing hardware on the carrier pulls the reset low before
powering up the Tegra, and the CPU is supposed to signal readiness,
and therefore bring peripherals out of reset by pulling PI4 high.
