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. Signed-off-by: Tom Rini <trini@konsulko.com>

ARM: ti: Update layout for MMC and eMMC (env and dfu) The problems with the current DFU layout are: MMC: The space allocated for u-boot is too small for the latest u-boot (>750KB). We need to increase it. eMMC uses a much bigger area (2MB). eMMC: region "u-boot.img.raw" overlaps the environment area and the region "spl-os-image.raw". both: region "spl-os-image.raw" is quite small and can't handle android kernels Fixing this requires growing some regions and moving others. Care has been taken to leave some room for further growth of "spl-os-args.raw". Also the "env" now appears in the dfu so that it's apparent that the region is not free space that can be used to grow "u-boot.img.raw". The MLO region is 0x100 sectors wide but the 0x100 are unused in case the MLO comes too overflow this areas. The total space allocated for those raw binaries is 16MB, of which 13+MB are reserved for the kernel image.
