New Revision: 1434
URL: http://flashrom.org/trac/flashrom/changeset/1434

Log:
Add initial Atmel AT49LH002 FWH/LPC chip support.

The chip code is untested, only one erase function out of two is currently
implemented, and unlocking/printlocking is not yet supported.

Thanks Mattias Mattsson <vitplister at gmail.com> for the initial patch!
