[PATCHv2] Add support for Numonyx N25Q064

[Niklas Söderlund]

Hi Idwer,

Here is the output working with a N25Q064 chip. Note I'm using a dediprog to 
talk to the chip and not an internal programmer. Hope the output is sufficient, 
is there any other output you need?

I also updated the email addresses in the patch, I wrote the patch a long time 
ago and did not realize I switched email since....

* Probe
$ ./flashrom --programmer dediprog
flashrom v0.9.5.2-rN25Q on Linux 3.2.13-1-ARCH (x86_64), built with libpci 3.1.9, GCC 4.7.0 20120324 (prerelease), little endian
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
Found Numonyx flash chip "N25Q064" (8192 kB, SPI) on dediprog.
No operations were specified.

* Read
$ ./flashrom --programmer dediprog -r dump.bin

Reading flash... done.

* Erase
$ ./flashrom --programmer dediprog -E

Calibrating delay loop... OK.
Found Numonyx flash chip "N25Q064" (8192 kB, SPI) on dediprog.
Erasing and writing flash chip... Erase/write done.

Note: The erase operation took a long time (~20min) but I verifyd that the chip 
was indeed erased correctly.

* Write
$ ./flashrom --programmer dediprog -w

Calibrating delay loop... OK.
Found Numonyx flash chip "N25Q064" (8192 kB, SPI) on dediprog.
Reading old flash chip contents... done.
Erasing and writing flash chip... Erase/write done.
Verifying flash... VERIFIED.
