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>

rockchip: sdram-common: fix wrong size for 4GB in 32bit SoC This is workaround for issue we can't get correct size for 4GB ram in 32bit system and available before we really need ram space out of 4GB, eg.enable ARM LAPE(rk3288 supports 8GB ram). The size of 4GB is '0x1 00000000', and this value will be truncated to 0 in 32bit system, and system can not get correct ram size. Rockchip SoCs reserve a blob of space for peripheral near 4GB, and we are now setting SDRAM_MAX_SIZE as max available space for ram in 4GB, so we can use this directly to workaround the issue.
