Allwinner SoCs feature something called a SID (Security ID) which should be available with
mainline kernel as /sys/bus/nvmem/devices/sunxi-sid0/nvmem. From the first bytes the SoC
model might be detectable once the SIDs are known. Unfortunately information in linux-sunxi
wiki is/was a bit sparse and outdated: https://linux-sunxi.org/SID_Register_Guide
The following list is based on linux-sunxi wiki contents and complemented with own checks
(crawling through sbc-bench submissions and conducting tests on own devices).

SoCs are sorted by chip ID, starting with 'old scheme':

A10 (1623)      162367*              --> 1623*
