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>
2017-09-04video: ipuv3_fb: skip IPU shutdown if IPU was not enabled beforeAnatolij Gustschin
Boards can skip display interface init using board_video_skip(). If display interface was not initialized (e.g. no ipuv3 framebuffer registered or IPU clock disabled), booting Linux stops due to the crash in IPU shutdown function, when accessing IPU registers. Check IPU clock and skip shutdown if clock is not enabled. Signed-off-by: Anatolij Gustschin <agust@denx.de>

2015-08-30video: discard empty video_set_lut implementationPeng Fan
Discard the empty video_set_lut function from platform video drivers. This commit "69d275458893eaec35229b589092c2a6bde5440f" introduces a weak function video_set_lut, so we do not need an strong function in platform drivers, which does nothing.

2014-04-30video: mxc_ipuv3_fb: stash frame buffer pointer in global data.Eric Nelson
This patch updates the i.MX video driver to store the frame-buffer address in the fb_base field of the global data structure *gd. By doing this, you can find the frame buffer address using the 'bdinfo' command: U-Boot > bdinfo arch_number = 0x00000EB9 ... FB base = 0x4F35F1C0 This is very useful when debugging display connections.

2011-10-13VIDEO: MX5: Switch MX5 to CONFIG_VIDEOStefano Babic
The framebuffer driver for MX5 is based on CONFIG_LCD. In the current implementation, there is a serious bug because the required memory is allocated before relocation, but the driver knows only later which is the resolution of the display. The patch switches the driver to CONFIG_VIDEO and the memory is allocated by the driver itself. We also need to switch the vision2 board code and config file in the same commit so that this commit will be bisectable.
