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>

sunxi: add gtbus-initialisation for sun9i On sun9i, the GTBUS manages transaction priority and bandwidth for multiple read ports when accessing DRAM. The initialisation mirrors the settings from Allwinner's boot0 for now, even though this may not be optimal for all applications (e.g. headless systems might want to give priority to IO modules). Adding a common callout to gtbus_init() from the SPL clock init with a weakly defined implementation in sunxi/clock.c to fallback to for platforms that don't require this.

sunxi: DRAM initialisation for sun9i This adds DRAM initialisation code for sun9i, which calculates the appropriate timings based on timing information for the supplied DDR3 bin and the clock speeds used. With this DRAM setup, we have verified DDR3 clocks of up to 792MHz (i.e. DDR3-1600) on the A80-Q7 using a dual-channel configuration.
