+1. Given the slow pace of hardware available that we can use (still
using hardware designed in the last decade as build machines), I have
low confidence in being able to use RVA23-capable hardware for build
machines (with upstream kernel support and all that) in less than 2
years.
So, without that, it's not even in the cards.
It's always possible that there's some hardware that it's 20x more
popular than the rest (think of the original RPi), in that case if
it's RVA23, it could tip the balance. But it seems unlikely, and in
any case unknown at the moment.
So this will have to be revisited in due time, probably not earlier
than 1 year from now.
Cheers.
