As long as it's supported by mainline Linux (which I suspect it is, but you'd have to check), then you should be able to make it work. I would probably follow the instructions based on one of the other armv7 Allwinner boards like the OLinuXino-Lime
https://archlinuxarm.org/platforms/armv7/allwinner/a10-olinuxino-lime. That'll have you download the generic armv7h image root tarball, then you'll just have to supply your own bootloader, which it looks like mainline u-boot supports this since there's
https://github.com/u-boot/u-boot/blob/master/configs/orangepi_r1_defconfig. I would install the u-boot package for whatever board your basing off of, then replace the u-boot binary from the package with the one you compile for your board and you should be OK to boot. Definitely YMMV, though.
