2018-06-18board: imx53: Always disable display before starting kernelLukasz Majewski1-0/+8
This patch prevents from the situation where we may end up with garbage displayed on the LCD panel. Such situation occurs when one performs "reboot -f" in Linux and then stop in U-boot (or observe the garbage on the screen during boot up). To prevent from such situation - the PWM pin is configured as GPIO and set to LOW. Signed-off-by: Lukasz Majewski <lukma@denx.de>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini4-10/+4
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>
2018-04-15boot: script: The boot.scr file for K+P's boardsLukasz Majewski1-0/+96
By using this file one can avoid cluttering <board>.h file with u-boot HUSH commands necessary for booting target device. With such approach the commands are stored only in one place and can be reused if needed. Signed-off-by: Lukasz Majewski <lukma@denx.de> Reviewed-by: Stefano Babic <sbabic@denx.de>
