[commit] r777 - trunk

Author: hailfinger
Date: 2009-11-25 03:07:30 +0100 (Wed, 25 Nov 2009)
New Revision: 777

Modified:
   trunk/ichspi.c
Log:
Kill hardcoded block erase on ICH SPI.
The existing code does not work for all SPI chips, and it just was a
band-aid to cope with locked down chipsets back in a time when there was
no eraseblock infrastructure.
Basically, this unbreaks a few SPI chips on ICH.
