New Revision: 1655
URL: http://flashrom.org/trac/flashrom/changeset/1655

Log:
Add support for Macronix MX25U1635E, MX25U3235E/F and MX25U6435E/F.

Macronix MX25U3235 is a 4MB (32Mbits) 1.8v SPI flash supporting QPI.
Code for it was refined after merging it from chromium:
Change-Id: I62c7db070254ba3ec68090e783f57b25a6e8d15a
Reviewed-on: https://gerrit.chromium.org/gerrit/44395

Reviewed-by: Randall Spangler <[email protected]>
Commit-Queue: Vincent Palatin <[email protected]>

Based on that support for MX25U1635E and MX25U6435E/F was added
by Stefan Tauner.
Also, add a feature flag for QPI-enabled chips: FEATURE_QPI.
