The Allwinner A100 SoC has been around for a while, mostly on cheap tablets, but didn't generate much interest in the community so far. There were some efforts by two Allwinner employees in 2020, which led to basic upstream Linux support for that SoC, although this momentum dried up pretty quickly, leaving a lot of peripherals unsupported.
The A100 was silently replaced with the seemingly identical Allwinner A133, which is reportedly a better bin of the A100. So far we assume that both are compatible from a software perspective. There are some more devices with the A133 out there now, so people are working on filling the gaps, and adding U-Boot (and TF-A) support.
Based on the just added pinctrl, clock and DRAM support, this adds the missing bits, mostly addresses and values for the SPL.
The A133 seems to be an predecessor to the H6, so we can share a lot of code with that (and the H616 code), and just need to adjust some details.
