[flashrom] FYI: flashrom output for Altera EPCQ16

[Salvador Eduardo Tropea]

Hi:

Just a comment: the patches I sent for the layout stuff are oriented to 
solve this issue. I use flashrom for FPGA bitstreams.
Once the layout stuff is finished flashrom will be really useful for FPGAs.
One important detail is that modern FPGAs support more than one 
configuration in the same memory. Additionally: when you use an SPI 
memory is common practice to store additional data, i.e. the firmware 
for a softcore.

Regards, SET
