+ *
+ *  chipshift - total number of address bits for the device which

+ *  pageadrlen - number of bytes minus one needed to hold the

+ *               mind that when a read or write is done to a

+ *               8 bits at a time. This structure member is used
+ *               by the read/write routines as a loop index for
+ *               shifting the address out 8 bits at a time.
+ *
+ *  erasesize - size of an erase block in the flash device.
