1st step to provide mode to help reviewing devices.

Mostly repurposing functionality that was already there.
Next stepts: quick RAM bandwidth measurements with mbw,
listing relevant software components, e.g. GCC, OpenSSL
and other versions, check of kernel version and printing
whether the kernel in question is out of support or not
based on https://endoflife.date/linux. Also planned:
Check whether the used kernel is an upstream one or some
smelly vendor BSP kernel.
