That's my biggest problem with personally enjoying RISC-V. I'd love to play with an application-class RISC-V processor, writing an OS for it and the like, but I'm waiting on a chip that's publicly well-documented in English.
I find the most useful there is the JH7110 TRM specifically.
There's links to a bunch more over here[1].
