i was reading a cxl whitepaper and apparently you can use cxl 3.0 over pcie
3.0's physical layer (8 Gbaud) which could be doable for our cpu... maybe
it even supports pcie 2.0 (5 Gbaud) which the ecp5-5g can do.

apparently you can become a cxl adopter for free, maybe the spec (the one
you get as a member) is licensed such that implementations of cxl can be
libre hardware, i'd have to see.
