This is the text on the manual:

Intel Advanced+ Boot Block Flash Memory (C3)
28F800C3, 28F160C3, 28F320C3, 28F640C3 (x16)
< http://www.intel.com/design/flcomp/datashts/290645.htm >

and the flash on the board is 28F160C3B(8?)C70.

I've set the buswidth to 2, since it's 16Mbit memory, the flash size is 2MB.

However, I've not defined any partitions on the memory (yet); how to do it for 
PCI flash devices? A separate driver?

Thanks,
Amit.
