[flashrom] [commit] r830 - trunk

[svn at flashrom.org]

Author: hailfinger
Date: 2010-01-06 17:09:10 +0100 (Wed, 06 Jan 2010)
New Revision: 830

Modified:
   trunk/buspirate_spi.c
   trunk/flash.h
   trunk/serial.c
Log:
Move OS-dependent serial code from buspirate_spi.c to serial.c and
rename a few functions to make it obvious that they are generic and not
specific to the Bus Pirate.
