It really is pretty specific to the rpi family, for a pair of reasons:

 - The hardware is just crappy, buggy, limited, hard to work with.

 - Documentation needed to write device drivers is not openly
available, and getting an NDA in place with broadcom never seems to
happen despite people over the years saying they would work to make it
happen.

For inexpensive low-power boards... For the 32-bit world, the
Allwinnner hardware is probably best supported, with imx6 a close
second.  For 64-bit I'd say it's the rockpro stuff.
