Greetings,
I've been playing with this as well. Depending on the motherboard, etc. the full size of the flash may not be mapped in.
It's probably worthwhile to look around in user space using /dev/mem to try to find the actual size of the mapped in portion. The flash part will respond to a JEDIC probe.
G'day, sjames

some output from printks I added:

it finds the part it sets the 0x4e register to 1 for enabling write hey! same register as the piix4e -- think this is a coincidence? it does the ioremap of the last (BIG) 16 MB of memory (WOW!) Then it does a JEDEC probe.
Do JEDEC probes really work with this 82802AB part?
They must have but ... Eric?
