I like this, as it removes assumptions from the code.
FWIW.

I think I finally found what was bugging me with it.
Granted, there are cases where we don't want two devices per bus, but
this is a requirement unrelated to the maximum number of busses and
devices: this is simply du

From: Rogan Dawes
Some SATA controllers can operate in an IDE compatible mode (e.g. mvsata)
but will only ever have a single device per bus.
This allows the upcoming DNS323 port to properly identify and use

Some SATA controllers can operate in an IDE compatible mode (e.g. mvsata)
but will only ever have a single device per bus.
This allows the upcoming DNS323 port to properly identify and use
