Thanks for the suggestions.  I finally found it in the wee hours this 
morning, and it was operator error.  The CY14 by default powers up in the 
write protect state and from the factory is erased to all zeros.  So my 
writes and subsequent reads appeared to fail by the "fact" that I could 
never read what I wrote.  Guess I need better reading glasses in my old 
age :-/

Anyway, I'm happily up and talking using the Freescale SPI driver and 
spidev.  Thanks for the help and sorry for the noise on the list.
