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 imports v11 of "Jetson TK1 Development Platform Pin Mux" from
https://developer.nvidia.com/embedded/downloads.
The new version defines the mux option for the MIPI pad ctrl selection.
The OWR pin no longer has an entry in the configuration table because
the only mux option it support is OWR, that feature isn't supported, and
hence can't conflict with any other pin. This pin can only usefully be
used as a GPIO.

The PMIC is configured such that its GPIOs have the correct configuration
at power-up, so no programming is required.
In fact, the current programming is actively wrong, since:
(a) the AS3722 driver configures the GPIO to be an output before setting
its output value, which causes a 0v glitch on the output.
(b) the AS3722 driver configures the GPIO to drive a high voltage from its
VSUP_GPIO power source rather than its VDD_GPIO_LV power source, so the pin
drives 5V not 1.8V as desired.
Solve these problems by removing the code which configures the PMIC GPIOs.
Note that this patch was tested directly on top of v2016.01; since then,
commit 96350f729c42 "dm: tegra: net: Convert tegra boards to driver model
for Ethernet" prevents PCIe from being initialized. Alternatively, simply
revert that commit to get PCIe Ethernet working again, then apply this
patch to test.

After consulting with some of the SPDX team, the conclusion is that
Makefiles are worth adding SPDX-License-Identifier tags too, and most of
ours have one. This adds tags to ones that lack them and converts a few
that had full (or in one case, very partial) license blobs into the
equivalent tag.

T124/210 requires some specific configuration (VPR setup) to
be performed by the bootloader before the GPU can be used.
For this reason, the GPU node in the device tree is disabled
by default. This patch enables the node if U-boot has performed
VPR configuration.
Boards enabled by this patch are T124's Jetson TK1 and Venice2
and T210's P2571.

Syseng has revamped the Jetson TK1 pinmux spreadsheet, basing the content
completely on correct configuration for the board/schematic, rather than
the previous version which was based on the bare minimum changes relative
to another reference board.
The new spreadsheet sets TRISTATE for any input-only pins. This only works
correctly if the global CLAMP bit is not set, so the Jetson TK1 board code
has been adjusted accordingly. Apparently syseng have changed their mind
since the previous advice that this needed to be set:-/

When the CPU is in non-secure (NS) mode (when running U-Boot under a
secure monitor), certain actions cannot be taken, since they would need
to write to secure-only registers. One example is configuring the ARM
architectural timer's CNTFRQ register.
We could support this in one of two ways:
1) Compile twice, once for secure mode (in which case anything goes) and
once for non-secure mode (in which case certain actions are disabled).
This complicates things, since everyone needs to keep track of
different U-Boot binaries for different situations.
2) Detect NS mode at run-time, and optionally skip any impossible actions.
This has the advantage of a single U-Boot binary working in all cases.
(2) is not possible on ARM in general, since there's no architectural way
to detect secure-vs-non-secure. However, there is a Tegra-specific way to
detect this.
This patches uses that feature to detect secure vs. NS mode on Tegra, and
uses that to:
* Skip the ARM arch timer initialization.
* Set/clear an environment variable so that boot scripts can take
different action depending on which mode the CPU is in. This might be
something like:
if CPU is secure:
load secure monitor code into RAM.
boot secure monitor.
secure monitor will restart (a new copy of) U-Boot in NS mode.
else:
execute normal boot process

This controller was introduced on Tegra114 to handle XUSB pads. On
Tegra124 it is also used for PCIe and SATA pin muxing and PHY control.
Only the Tegra124 PCIe and SATA functionality is currently implemented,
with weak symbols on Tegra114.
Tegra20 and Tegra30 also provide weak symbols for these functions so
that drivers can use the same API irrespective of which SoC they're

Nyan-big is a Tegra124 clamshell board that is very similar to venice2, but
it has a different panel, the sdcard cd and wp sense are flipped, and it has
a different revision of the AS3722 PMIC.
This is the Acer Chromebook 13 CB5-311-T7NN (13.3-inch HD, NVIDIA
Tegra K1, 2GB). The display is not currently supported, so it should
boot on other nyan-based Chromebooks also, but only the device tree for
nyan-big is provided here.
The device tree file is from Linux but with features removed which are
unlikely to be supported in U-Boot soon (regulators, pinmux). Also the

This is an implementation of GPIOs for Tegra that uses driver model. It has
been tested on trimslice and also using the new iotrace feature.
The implementation uses a top-level GPIO device (which has no actual GPIOS).
Under this all the banks are created as separate GPIO devices.
The GPIOs are named as per the Tegra datasheet/header files: A0..A7, B0..B7,
..., Z0..Z7, AA0..AA7, etc.
Since driver model is not yet available before relocation, or in SPL, a
special function is provided for seaboard's SPL code.

This commit adds:
- arch/${ARCH}/Kconfig
provide a menu to select target boards
- board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
set CONFIG macros to the appropriate values for each board
- configs/${TARGET_BOARD}_defconfig
default setting of each board
(This commit was automatically generated by a conversion script
based on boards.cfg)
In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.
But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.
