I don't have something constructive to say here, just want to point out
that on efm32 there is something similar. It's called "Device
Information (DI) Page" and contains "calibration values, a
unique identification number and other useful data".

Currently it is unused in mainline, but in my tree I access it directly
to determine cpu type (part number, part family number and Production
ID), flash and ram size, and the calibration settings for the ADC.

Best regards
Uwe
