Dear Dirk Behme,

There are many such ad-hoc approaches, and most of them are just a
PITA.  If you are trying to optimize boot times, it is really a pain
if you have to wait for inherently slow devives like EEPROMs on a I2C
bus etc.

Also, this addresses only the first half of the problem - the source
of the information. The other half is how to pass the information to
the kernel (-> DT).

Best regards,

Wolfgang Denk

The only solution is ... a balance of power. We  arm  our  side  with
exactly  that  much  more.  A balance of power -- the trickiest, most
difficult, dirtiest game of them all. But the only one that preserves
both sides.
