Detect boot (device) type

Hello,

is there a simple (or recomended) way a boot-time driver can detect
whether the system is booting from USB/network/SD card, or other
supported device type?

Best regards
Martin Dráb

What bigger problem are you trying to solve?

Hello,

unfortunately, I seem to be unable to give information about the bigger
problem I am trying to solve, since the problem is quite concrete one
and I would break my NDA by giving the information (at least for the
following two months).

However, I hopefully fixed the problem by other means so I do not need
to detect over which “bus” the system is booting.

best regards
