17 ROM driver code to communicate with chips which are mapped
18 physically into the CPU's memory. You will need to configure
19 the physical address and size of the flash chips on your
20 particular board as well as the bus width, either statically
21 with config options or at run-time.

58 in octets. For example, if you have a data bus width of 32
59 bits, you would set the bus width octet value to 4. This is
60 used internally by the CFI drivers.
61 Ignore this option if you use run-time physmap configuration
