Recommended properties :

- bank-width : Width of the flash data bus in bytes. Required
for the NOR flashes (compatible == "direct-mapped" and others) ONLY.
- partitions : Several pairs of 32-bit values where the first value is
partition's offset from the start of the device and the second one is
partition size in bytes with LSB used to signify a read only
partititon (so, the parition size should always be an even number).

- partition-names : The list of concatenated zero terminated strings
representing the partition names.
- probe-type : The type of probe which should be done for the chip

Example:
