Detailed Description

The permanent_storage namespace provides all necessary facilities related to permanently storing data (into EEPROM) on the MMU unit.

It uses some clever logic/wear levelling/data structure on top of the raw EEPROM API. The code was originally written by Marek Bel for the previous MMU firmware.
