[flashrom] [commit] r1075 - trunk

[repository service]

Author: mkarcher
Date: Sun Jul 11 23:33:31 2010
New Revision: 1075
URL: http://flashrom.org/trac/coreboot/changeset/1075

Log:
Add support for the AMIC A25L80P.  This is a 1 MB SPI
chip that seems to be straightforwardly related to the AMIC A25L40PU, which
has half the capacity but is otherwise identical.

Datasheet is at http://www.amictechnology.com/pdf/A25L80P.pdf

flashrom -VE, -Vr, and -Vw has been tested using the AMD SB7x0 interface.
Everything works fine...  at least, I used it to upgrade my BIOS and I've
been able to reboot.
