Hi,
According to the pictures, R2.0 differs from R3.0 by the number of PCIe slots (maybe some ports will not work) and it looks like they are using a different SuperIO chip (you may not see the console in the COM port), maybe there are other differences... Regardless, you can try to run coreboot on your board, although I recommend analyzing the pad configuration using inteltool (get a dump of the registers of the gpio controller):
$ sudo ./inteltool -G
and then compare this with the dump from R2.0 - https://github.com/maxpoliak/inteltool-examples/blob/master/inteltool-asrock...
If there are differences, then you need to fix them in https://github.com/coreboot/coreboot/blob/master/src/mainboard/asrock/h110m/...
This will avoid possible burnout of chips, transistors or any other elements on the board.

What did you find out about the differences between R2.0 and R3.0?
From the ASRock website it looks like they have different hardware layouts and the OEM BIOS packages are different. The specs are similar but slightly different. That's all I know.
Link to R2.0: https://www.asrock.com/mb/Intel/H110M-DVS%20R2.0/ Link to R3.0: https://www.asrock.com/mb/Intel/H110M-DVS%20R3.0/
