I pick them up in my github. 
(https://github.com/Caesar-github/rockchip/tree/wip/fixes-thermal-0425)

Can we add the following strings to match the loader (coreboot)?
  No matter, we can match the loader(coreboot) to bring up the evb board 
on now or in the future.

...,"google,rk3399evb-rev3", 
google,rk3399evb-rev2",google,rk3399evb-rev1","google,rk3399evb-rev0"

Bring up my evb board:
...
Compat preference: google,rk3399evb-rev0
Config conf@4, kernel kernel@1, fdt fdt@4, compat google,rk3399evb-rev0 
(match) rockchip,rk3399-evb rockchip,rk3399
Config conf@3, kernel kernel@1, fdt fdt@3, compat rockchip,r88 
rockchip,rk3368
Config conf@2, kernel kernel@1, fdt fdt@2, compat geekbuying,geekbox 
rockchip,rk3368
Config conf@1 (default), kernel kernel@1, fdt fdt@1, compat 
rockchip,rk3368-evb-act8846 rockchip,rk3368
Choosing best match conf@4.
