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.

global: Move remaining CONFIG_SYS_* to CFG_SYS_* The rest of the unmigrated CONFIG symbols in the CONFIG_SYS namespace do not easily transition to Kconfig.

arm: highbank: Limit FDT and initrd load addresses So far on Highbank/Midway machines U-Boot only ever uses 512MB of DRAM, even though the machines have typically 4GB and 8GB, respectively. That means that so far we didn't need an extra limit for placing the DTB and initrd, as the 512MB are lower than the kernel's limit ("lowmem", typically 768MB). With U-Boot now needing to learn about the actual memory size (to correctly populate the EFI memory map), it might relocate fdt and initrd to the end of DRAM, which is out of reach of the kernel. So add limiting values to the fdt_high and initrd_high environment variables, to prevent U-Boot from using too high addresses.
