   2 # Up to two entries are valid, in this case the redundant
   3 # environment sector is assumed present.
   4 # Notice, that the "Number of sectors" is not required on NOR and SPI-dataflash.
   5 # Futhermore, if the Flash sector size is omitted, this value is assumed to
   6 # be the same as the Environment size, which is valid for NOR and SPI-dataflash
   7 # Device offset must be prefixed with 0x to be parsed as a hexadecimal value.
