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>

serial, ns16550: bugfix: ns16550 fifo not enabled commit: 65f83802b7a5b "serial: 16550: Add getfcr accessor" breaks u-boot commandline working with long commands sending to the board. Since the above patch, you have to setup the fcr register. For board/archs which enable OF_PLATDATA, the new field fcr in struct ns16550_platdata is not filled with a default value ... This leads in not setting up the uarts fifo, which ends in problems, when you send long commands to u-boots commandline. Detected this issue with automated tbot tests on am335x based shc board. The error does not popup, if you type commands. You need to copy&paste a long command to u-boots commandshell (or send a long command with tbot) Possible boards/plattforms with problems: ./arch/arm/cpu/arm926ejs/lpc32xx/devices.c ./arch/arm/mach-tegra/board.c ./board/overo/overo.c ./board/quipos/cairo/cairo.c ./board/logicpd/omap3som/omap3logic.c ./board/logicpd/zoom1/zoom1.c ./board/timll/devkit8000/devkit8000.c ./board/lg/sniper/sniper.c ./board/ti/beagle/beagle.c ./drivers/serial/serial_rockchip.c Signed-off-by: Heiko Schocher <hs@denx.de> Signed-off-by: Ladislav Michl <ladis@linux-mips.org> Tested-by: Adam Ford <aford173@gmail.com> Reviewed-by: Tom Rini <trini@konsulko.com>
