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wiki is/was a bit sparse and outdated: https://linux-sunxi.org/SID_Register_Guide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*

With ARMv7 SoCs (or ARMv8 SoCs booting a 32-bit kernel) dmesg output starts with a line identifying core type and stepping of cpu0:
CPU: ARMv7 Processor [410fc051] revision 1 (ARMv7), cr=10c5387d  <-  Cortex-A5 / r0p1 / Amlogic S805
CPU: ARMv7 Processor [410fc073] revision 3 (ARMv7), cr=10c5387d  <-  Cortex-A7 / r0p3 / Exynos 5422
CPU: ARMv7 Processor [410fc072] revision 2 (ARMv7), cr=10c5387d  <-  Cortex-A7 / r0p2 / MediaTek MT6589/TMK6588

Recent Rockchip BSP kernels include something like this in dmesg output: rockchip-cpuinfo cpuinfo: SoC : 35880000

35280000 --> Hlink H28K
35281000 --> Hlink H28K
35661000 --> Quartz64, RK3566 EVB2 LP4X V10 Board, Firefly RK3566-ROC-PC
35662000 --> EmbedFire LubanCat-Zero, RK3566 BOX DEMO V10 ANDROID Board, Radxa Zero 3, Rock 3C, Radxa CM3,
             Orange Pi 3B, Orange Pi CM4
35681000 --> only early RK3568 devices showed this silicon revision (e.g. Firefly RK3568-ROC-PC/AIO-3568J,
             Radxa E25)
35682000 --> AIO-3568J HDMI, CPdevice Spring2 Plus Board, Firefly RK3568-ROC-PC HDMI, Forlinx OK3568-C Board,
