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: mxs: Receive r0 and r1 passed from BootROM Make sure value in register r0 and r1 is preserved and passed to the board_init_ll() and mxs_common_spl_init() where it can be processed further. The value in r0 can be configured during the BootStream generation to arbitary value, r1 contains pointer to return value from CALL'd function. This patch also clears the value in r0 before returning to BootROM to make sure the BootROM is not confused by this value. Finally, this patch cleans up some comments in the start.S file.
