When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

Move (and rename) the following CONFIG options to Kconfig:
CONFIG_DAVINCI_MMC (renamed to CONFIG_MMC_DAVINCI)
CONFIG_OMAP_HSMMC (renamed to CONFIG_MMC_OMAP_HS)
CONFIG_MXC_MMC (renamed to CONFIG_MMC_MXC)
CONFIG_MXS_MMC (renamed to CONFIG_MMC_MXS)
CONFIG_TEGRA_MMC (renamed to CONFIG_MMC_SDHCI_TEGRA)
CONFIG_SUNXI_MMC (renamed to CONFIG_MMC_SUNXI)
They are the same option names as used in Linux.
This commit was created as follows:
[1] Rename the options with the following command:
find . -name .git -prune -o ! -path ./scripts/config_whitelist.txt \
-type f -print | xargs sed -i -e '

s/CONFIG_TEGRA_MMC/CONFIG_MMC_SDHCI_TEGRA/g
s/CONFIG_SUNXI_MMC/CONFIG_MMC_SUNXI/g
'
[2] Commit the changes
[3] Create entries in driver/mmc/Kconfig.
(copied from Linux)
[4] Move the options with the following command
tools/moveconfig.py -y -r HEAD \
MMC_DAVINCI MMC_OMAP_HS MMC_MXC MMC_MXS MMC_SDHCI_TEGRA MMC_SUNXI
[5] Sort and align drivers/mmc/Makefile for readability

There are currently many places that define the list of all Tegra GPIOs;
the DT binding header and custom Tegra-specific header file gpio.h. Fix
the redundancy by replacing everything with the DT binding header file.

This renames all the Tegra20 pinmux pins and functions so they have a
prefix which matches the type name.
The entries in tegra20_pingroups[] are all updated to remove the columns
which are no longer used.
All affected code is updated to match.

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.

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".

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.

Convert TEGRA20_ defines to either TEGRA_ or NV_PA_ where appropriate.
Convert tegra20_ source file and function names to tegra_, also.

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.

This commit uses the common Tegra board implementation instead of
