c79aa81dbc p2771-0000: Add support for framebuffer carveouts
If early firmware initialized the display hardware and the display
controllers are scanning out a framebuffer (e.g. a splash screen), make
sure to pass information about the memory location of that framebuffer
to the kernel before booting to avoid the kernel from using that memory
for the buddy allocator.

This same mechanism can also be used in the kernel to set up early SMMU
mappings and avoid SMMU faults caused by the display controller reading
from memory for which it has no mapping.

8317189737 p2771-0000: Pass Ethernet MAC to the kernel

the local-mac-address property (as passed to U-Boot from cboot) and the

a0dbc1314c ARM: tegra: Unify Tegra186 builds
Tegra186 build are currently dealt with in very special ways, which is
because Tegra186 is fundamentally different in many respects. It is no
longer necessary to do many of the low-level programming because early
boot firmware will already have taken care of it.

Unfortunately, separating Tegra186 builds from the rest in this way
makes it difficult to share code with prior generations of Tegra. With
all of the low-level programming code behind Kconfig guards, the build
for Tegra186 can again be unified.

As a side-effect, and partial reason for this change, other Tegra SoC
generations can now make use of the code that deals with taking over a
boot from earlier bootloaders. This used to be nvtboot, but has been
replaced by cboot nowadays. Rename the files and functions related to
this to avoid confusion. The implemented protocols are unchanged.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

9b643e312d treewide: replace with error() with pr_err()
U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

  # define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux.  (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// <smpl>
@@@@
-error
+pr_err
 (...)
// </smpl>

6dca554f23 ARM: tegra: fix ULPI PHY on Ventana and Seaboard
Commit ce02a71c23 "tegra: dts: Sync tegra20 device tree files with
Linux" enabled the ULPI USB port on Ventana, but made no attempt to ensure
that U-Boot code could handle this. In practice, various code is missing,
and various configuration options are not enabled, which causes U-Boot to
hang when attempting to initialize this USB port. This patch enables ULPI
PHY support on Ventana, and adds the required pinmux setup for the port to
operate. Note that Ventana is so similar to Seaboard that this change is
made in the Seaboard board file, which is shared with Ventana.

Seaboard also has the ULPI USB port wired up in hardware, although to an
internal port that often doesn't have anything attached to it. However,
the DT nodes for the USB controller and PHY had different status property
values, so the port was not initialized by U-Boot. Fix this inconsistency,
and enable the ULPI port, just like in the Linux kernel DT. This likewise
requires enabling ULPI support in the Seaboard defconfig.

10a03382f0 ARM: tegra: add p2771-0000 board support
P2771-0000 is a P3310 CPU board married to a P2597 I/O board. The
combination contains SoC, DRAM, eMMC, SD card slot, HDMI, USB micro-B
port, Ethernet, USB3 host port, SATA, PCIe, and two GPIO expansion
headers.

Currently, due to U-Boot's level of support for Tegra186, the only
features supported by U-Boot are the console UART and the on-board eMMC.
Additional features will be added over time.

U-Boot has so far been tested by replacing the kernel image on the device
with a U-Boot binary. It is anticipated that U-Boot will eventually
replace the CCPLEX bootloader binary, as on previous chips. This hasn't
yet been tested.

7fb82986be ARM: tegra: rm Jetson TK1 PMIC GPIO programming
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 96350f729c "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.

Note: There is an DP change also, caused by running board-to-uboot.py
script in the latest tegra-pinmux-script tree.

7cfde8117f tegra: nyan-big: Add additional clock and kernel init
We need to turn on all audio-related clocks for the Chrome OS kernel to
boot. Otherwise it will hang when trying to enable audio.

Also for Linux set up graphics driver video protection.

237c36379c ARM: tegra: move NVIDIA common files to arch/arm/mach-tegra
All the Tegra boards borrow the files from board/nvidia/common/
directory, i.e., board/nvidia/common/* are not vendor-common files,
but SoC-common files.

Move NVIDIA common files to arch/arm/mach-tegra/ to clean up
Makefiles.

As arch/arm/mach-tegra/board.c already exists, this commit renames
board/nvidia/common/board.c to arch/arm/mach-tegra/board2.c,
expecting they will be consolidated as a second step.
