f53dcc0e35 tegra: fdt: Ensure that the console UART is enabled
Many tegra boards have the console UART node disabled. With livetree this
prevents serial from working since it does not 'force' the console to be
bound. Updates the affected boards to fix this error.

The boards were checked with:

for b in $(grep  tegra boards.cfg  |grep -v integrator | \
		awk '{print $7}' | sort); do
	echo $b;
	fdtgrep -c nvidia,tegra20-uart b/$b/u-boot.dtb |grep okay;
done

ce2f2d2ae7 ARM: tegra: pull Tegra30 SoC DT from Linux v4.7
The primary benefit of this change is that it adds all missing clocks and
resets properties to peripherals. This will allow peripheral drivers to
migrate to the standard clock and reset APIs in the future.

Main changes:
* Modification of PCIe memory region addresses. The HW memory layout is
  programmable, so this should work fine, and Beaver PCIe was tested
  without issue.
* Removal of pcie_xclk from the PCIe node and clock binding header. This
  clock doesn't exist and isn't used; only a reset with this ID exists.
* Conversion of SPI nodes to standard DMA bindings. U-Boot doesn't use
  DMA so isn't affected.
* Split of EHCI and USB PHY nodes. The EHCI nodes continue to contain all
  information required by U-Boot, so U-Boot is not affected.
* Changed the phy_type value for the second USB port. This required board
  DTs to be updated to keep the same configuration.
* Boards need to define the clk32k_in clock that feeds the Tegra PMC.
* Addition of tegra30-mc.h since tegra30.dtsi now includes it.
* Conversion of many magic numbers to named defines.
* Addition of many nodes not used by U-Boot.
* Node sort order fixes.

Remaining deltas relative to the Linux DT:
* None.

67748a73b1 mmc: tegra: use correct alias for SDHCI/MMC nodes
The Tegra MMC driver currently honors "sdhci" entries in /aliases. The
MMC core however uses "mmc" entries in /aliases. This difference will be
relevant once the Tegra MMC driver is converted to DM, and the MMC core
handles alias lookups. To avoid issues during that conversion, fix the
Tegra MMC driver and all Tegra DTs to use the same alias name as the MMC
core does.

9a06a1a3a1 ARM: tegra: fdt: Add 'non-removable' property to all eMMC nodes
During debug of the DM_MMC changes to the Tegra MMC driver, I
noticed that the 'removable' property wasn't being set correctly
for the eMMC parts on most Tegra boards. Since the kernel DTS has
this property set correctly, it should be in U-Boot's Tegra DT too.

affe026928 ARM: tegra: Enable PCIe on Beaver
The Beaver has an ethernet NIC connected to the PCIe bus. Enable the
PCIe controller and the network device driver so that the device can
boot over the network.

In addition the board has a mini-PCIe expansion slot.

c369139234 tegra: dts: Add serial port details
Some Tegra device tree files do not include information about the serial
ports. Add this and also add information about the input clock speed.

The console alias needs to be set up to indicate which port is used for
the console.

Also add a binding file since this is missing.

Series-changes; 5
- Add full serial port nodes from Linux tree (commit fc9d4dbe)
- Use /chosen/stdout-path instead of /aliases/console to specify the console

e6607cffef ARM: tegra: enable USB device mode and UMS on some boards
For each of Jetson TK1, Venice2, and Beaver:

- Enable the first USB controller in DT, and describe its configuration.

- Enable USB device/gadget support. This allows the user to type e.g.
  "ums 0 mmc 0" at the command-line to cause U-Boot to act a USB device
  implementing the USB Mass Storage protocol, and expose MMC device 0
  that way.

This allows a host PC to mount the Tegra device's MMC, partition it, and
install a filesystem on it.

5ab502cb89 dts: move device tree sources to arch/$(ARCH)/dts/
Unlike Linux Kernel, U-Boot historically had *.dts files under
board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/.

I think arch/$(ARCH)/dts dicretory is a better location
to store both *.dts and *.dtsi files.

For example, before this commit, board/xilinx/dts directory
had both Microblaze dts (microblaze-generic.dts) and
ARM dts (zynq-*.dts), which are totally unrelated.

This commit moves *.dts to arch/$(ARCH)/dts/ directories,
allowing us to describe nicely mutiple DTBs generation in the next commit.
