i have olimexs sunxi boards and they have a blob bootloader with no sources so they are not completely covered, only hardware as it mentions. but this is common for arm of course.
on the flipside thats still leagues above rpis and you can buy the chips for your own use unlike the broadcom ones
Thun sunxi family of chips is really badly supported by the manufacturers, but the mainlining effort (as documented at https://linux-sunxi.org/Linux_mainlining_effort) is going pretty well. It's still a bit risky if you don't buy an entire integration package from one of the big vendors and at that point you're NDA'ed so hard you might as well go Broadcom or Qualcomm.
