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. Signed-off-by: Tom Rini <trini@konsulko.com> 2018-05-06 21:58:06 +00:00			`// SPDX-License-Identifier: GPL-2.0+`
ARM: tegra: add core Tegra186 support This adds the bare minimum code to support Tegra186, with UART and eMMC working. The empty gpio.h is required because <asm/gpio.h> includes it. A future cleanup round may be able to solve this for all Tegra generations at once. mach-tegra/Makefile is adjusted not to compile anything for Tegra186, but instead to defer everything to mach-tegra/tegra186/Makefile. This allows the SoC code to pick-and-choose which of the C files in the "common" mach-tegra/ directory to compile in based on the SoC's needs. Most of the code is not valid for Tegra186, and this approach removes the need for mach-tegra/Makefile to contain many SoC-specific ifdefs. This approach may be applied to all other Tegra SoCs in a future cleanup round. board186.c is introduced to replace board.c and board2.c. These files currently contain a slew of SoC- and board-specific code that is not valid for Tegra186. This approach avoids adding yet more ifdefs to those files. A future cleanup round may refactor most of board*.c into board-/ SoC-specific functions files thus allowing the top-level functions like board_init_early_f to be shared again.

ARM: tegra: add SoC-level hook for board_late_init() Extend the Tegra186 implementation of board_late_init() to call a per-SoC "hook" function. This will allow SoC-specific (rather than Tegra-wide) functionality to be implemented without the core Tegra code needing to be aware of the details. While board186.c is currently only used for Tegra186, it should be applicable to any other future SoC, and perhaps its simple design could be back-ported to older SoCs in the future too.
