[flashrom] [RFC] National Semiconductor DP83815 NIC patch

Hi,

I have a couple of Netgear FA311 network cards, which have DP83815DVNG 
chips on board, and a space to mount a 32-pin boot ROM socket. Looking 
at the datasheet for the chip I have created this patch.

The datasheet suggests that reads and writes must be done 32 bits at a 
time, and only at 32 bit offsets. This seems strange for chips which 
have an 8 bit data bus.

I don't think this code is ready for inclusion in flashrom yet, but if 
anyone has a card with this chip and can test it out then give it a go. 
I'm pretty sure it won't just work though. It might even destroy your 
computer/house/planet.

I can't test it yet because the cards don't have a 32pin socket mounted 
on them. If and when I can add one then I can do some tests.

This is my first 'large' patch so let me know what I have got wrong. :)
