Because there is no "official" BF16 standard (beyond interchange
format) and because other vendors have made incompatible choices (so
no de-facto standard either), we will need to define the RISC-V BF16
Some people are working towards this as part of alternate FP group
proposal - there are a few details that need some thought.
Once this is specified, there can be reference implementations
