- Byte-offset of the partition table in the first flash chip.
- The default value is 64kB and should not be changed unless
- you know exactly what you are doing. The only valid reason
- for changing this is when the flash block size is bigger
- than 64kB (e.g. when using two parallel 16 bit flashes).
