Hi,
what's the difference between portwidth & chipwidth in file cif_flash.c? 
what does "8M × 8 BITS" mean?

Best regards
enorm

Assuming the system has 4 flash chips, and each flash chip is 16 bits =
witdh.
So, the portwidth is 64bits, that is 4 *16. the chipwidth is 16bits.

Looks up some flash datasheet, you will perfect know what is the =
meaning.
