In my case I use the eeprom (or fram) to store the environment. So
with this I can erase the env-partition simply by calling 'erase
/dev/env0'.
So it's more like a convenience function. Or is there a other
possibility to easily erase a partition completely? The memset-command
is not really suitable because I have to pass the size as an argument.
