Pull request: u-boot-sunxi/master for 2022.04 (part 2)

[Andre Przywara]

Hi Tom,

this is the promised second part of the sunxi PR for 2022.04, albeit
technially outside of the merge window. We were working on this full
steam since the beginning of the year, and it deserves to be merged,
I think.
The main attraction is support for the F1C100s SoC, which sports a
venerable ARM926 core. Support for this SoC and the LicheePi Nano board
has been in Linux for years, and U-Boot patches were posted mid last
year already.
The new SoC using ARMv5 also means that the bulk of the new code should
not touch any existing boards, although we did some refactorings first,
of course, which actually cleans up some existing sunxi code.

Compile tested for all 160 sunxi boards, and briefly tested on BananaPi M1,
OrangePi Zero, Pine64 and Pine-H64. Tested by others on their boards,
including F1C100s and F1C200s devices.

Thanks,
Andre
