Hmm, how common is it for BMCs to have a USB port?  Perhaps it's more so
than I realize, but at least in my (admittedly somewhat limited)
experience I've yet to encounter one that does, so I'm wondering how
appropriate these options are for the aspeed-g5 defconfig if they might
just end up as a bunch of code that's never executed on most BMCs.
