2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>
2016-01-30video: Use fractional units for X coordinatesSimon Glass
With anti-aliased fonts we need a more fine-grained horizontal position than a single pixel. Characters can be positioned to start part-way through a pixel, with anti-aliasing (greyscale edges) taking care of the visual effect. To cope with this, use fractional units (1/256 pixel) for horizontal positions in the text console.

2016-01-20dm: video: Add a driver for a rotated text consoleSimon Glass
Sometimes the console must be rotated. Add a driver which supports rotating the text clockwise to 90, 180 and 270 degrees. This can support devices where the display is rotated for mechanical reasons. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
