Merge https://source.denx.de/u-boot/custodians/u-boot-sunxi
To quote Andre: One prominent feature is the restructering of the clock driver, which allows to end up with one actual driver for all variants, although we still only compile in support for one SoC. Also contained are some initial SPI fixes, which should fix some problems, and enable SPI flash support for the F1C100s SoC. Those patches revealed more problems, I will queue fixes later on, but for now it should at least still work. Apart from some smaller fixes (for instance for NAND operation), there is also preparation for the upcoming Allwinner D1 support, in form of the USB PHY driver. There are more driver support patches to come. The gitlab CI completed successfully, including the build test for all 160 sunxi boards. I also boot tested on a few boards, but didn't have time for more elaborate tests this time.
