[riot-devel] Save data in ROM

Hi Baptiste,

that is actually something being planned (although with low prio). Some 
of the older boards have this already implemented (look at the config 
module for the msba2 and msb-430). For streamlining this all across 
RIOT, I thing what we should to is to create a generic architecture like 

| light-weight persistent storage API              |
| some kind of (static) multiplexing               |
| low-level  | low-level  | low-level | I2C    | . |
| SPI flash  | EEPROM     | on-chip   | EEPROM | . |
| driver     | driver     | flash dri | driver | . |

Through the API on top it should subsequently then also be possible to 
implement a real file system on top of this. In the end it think the 
most important part is the separation of API and the actual drivers for 
different storage 'devices'!

Again, this is just a rough draft, feel free to advance this discussion!
