[coreboot] [flashrom] r551 - trunk

Author: hailfinger
Date: 2009-05-27 13:40:08 +0200 (Wed, 27 May 2009)
New Revision: 551

Modified:
   trunk/spi.c
   trunk/w39v080fa.c
Log:
Use consistent naming for local chip ID variables. Every chip besides
SPI and w39v080fa uses id1/id2 as local variable names to store ID
responses from the flash chip.
This eases grepping a lot. As a bonus, it also frees up some names to be
used as parameters.
