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> |

Overview
--------
The LS1046A Reference Design Board (RDB) is a high-performance computing,
evaluation, and development platform that supports the QorIQ LS1046A
LayerScape Architecture processor. The LS1046ARDB provides SW development
platform for the Freescale LS1046A processor series, with a complete
debugging environment. The LS1046A RDB is lead-free and RoHS-compliant.
