Some of the changes are similar to the fixes we have at Juniper ourselves, so getting the driver sync'd up is a good idea. Not to mention that we have added support for the SPI interface. Just a quick question: is an array different from 2 independent CFI devices on the same bus? I mean: can we support an array by having 2 driver instances? Thanks, -- Marcel Moolenaar xcllnt@mac.com
