New Revision: 1594
URL: http://flashrom.org/trac/flashrom/changeset/1594

Log:
Add support for Eon EN25F64.

Its ID was spotted in an ICH descriptor region update by Jetway:
http://paste.flashrom.org/view.php?id=1217 and is used on ASUS P8B75-V
boards according to some forum posts (2 chips per board actually).

No datasheet was found, so most values are just guessed from the EN25F32.
