No, not at all. This feature performs a one-time scanning of some
inputs at power on (or at reset). This can be buttons that a user
presses (and holds pressed) when power cycling / resetting the
device, or DIP switches, or similar.
We only record the state to switch on a specific boot mode.
We do not need any interactivity during the POST itself.
The same could be implemented for example by setting a specific
envrionment variable, or similar.

I see this in board/xes/xpedite1000/xpedite1000.c and
board/sandburst/common/sb_common.c only, and I have no idea what it is
supposed to mean or how it is supposed to work. You have to ask this
the implementers of that specific code. I haven't seen it before.
Best regards,
Wolfgang Denk
