Just wanted to see if RISC-V architecture is attractive for OpenBSD

I hear it's only truly open if you're part of their exclusive "club".
Otherwise it's as much "you take what you're given" as any other
architecture.
RISC-V architecture, and a few implementations are released under BSD licence.
In contrast, ARM Holdings or MIPS Technologies don't allow others to use their
architectures without paying royalty fees. For example, the Chinese Academy of
Sciences designed Loongson processor from the scratch, but had to pay to
MIPS Technologies in order to base it on the MIPS IV instruction set.
