I have an ignorant question about wishbone. Is it possible that there is
functionality in OpenCAPI that would be beneficial to extend wishbone
with, and not time prohibitive (not for Oct 2020 tapeout but for the
quad-core gpu capable version)? This is assuming that implementing a
part of OpenCAPI in wishbone is legally permitted, which I am also
ignorant of.
