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.

ARM: meson: add unique MAC address generation Add support for generating an unique MAC address using the SoC internal serial number from the Secure Monitor interface. The algorithm generates an unicast locally administered 6bytes minus 2bits address using an crc16 of the serial for the top 16bits with the lower 2 bits masked to setup the unicast locally administered property and a crc24 for the lower 24bits.
