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>

video: add STM32 LTDC display controller The STM32 LTDC display controller provides a parallel digital RGB and signals for horizontal, vertical synchronization, Pixel Clock and Data Enable as output to interface directly to a variety of LCD and TFT panels. The LTDC main features are: - 24-bit RGB Parallel Pixel Output, Programmable timings & polarity for HSync, VSync and Data Enable. - 2 layers with Blending, Color Keying, Window position & size, Dithering, Background color, Color Look-Up Table (CLUT). - Supported layer color formats: ARGB8888, RGB888, RGB565, ARGB1555, ARGB4444, L8 CLUT, AL44 & AL88 This LTDC driver: - supports: RGB parallel output with timings & polarity, 1 layer in RGB565. - supports but with hard-coded configurations: blending, window position & size (crop), background color. - does not support yet: rgb888, argb8888, 8-bit clut, dithering. This LTDC driver is compatible with all stm32 platforms with the LTDC IP and has been tested on stm32 f746-disco board. Signed-off-by: Philippe CORNU <philippe.cornu@st.com>

help
STM32 supports many video output options including RGB and
DSI. This option enables these supports which can be used on
devices which have RGB TFT or DSI display connected.
