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).

We arm our side with exactly that much more. A balance of power -- the trickiest, most difficult, dirtiest game of them all.
