What exact behaviour does vromoff influence? You mention I/O registers,
but RAM offset feels like it may be related to MEM or FWH LPC cycles
instead?

I'm trying to understand whether we can find some common ground with
controlling e.g. Aspeed's BMCs LPC peripherals based on Arnd's query[1],
but the description is a bit too vague right now for me to be able to do
that.
