I may of been joking with respect to the RPI3, but at the same time I do know that the RockPro64 exists and does have that PCIe slot I want, I also know that Michael Dexter has one he would loan me should I wish to investigate our state of support. > FreeBSD runs on Cavium/Marvell ThunderX and ThunderX2 and now on > Ampere eMAG with the WIP discussed in PR 237055.
