Author: hailfinger

New Revision: 483
Added:
trunk/dummyflasher.c
Modified:
trunk/Makefile
trunk/flash.h
trunk/flashrom.8
trunk/flashrom.c
Log:
Add a dummy external flasher which just prints each operation.
Usage:
flashrom --programmer dummy
This is a great way to test flashrom without root access.
