Add bus type support to the dummy external programmer
The syntax is explained in the man page.
Example: flashrom -p dummy=lpc,fwh
Tested, works perfectly. ;-)
As a nice benefit, it allows easy testing of the "probe only compatible
flashes" patch.
Corresponding to flashrom svn r559.

+The dummy programmer has an optional parameter specifying the bus types it
+should support. For that you have to use the
+.B "flashrom -p dummy=type"
+syntax where
+.B type
+can be any comma-separated combination of
+.B parallel lpc fwh spi all
+in any order.
+.sp
+Example:
+.B "flashrom -p dummy=lpc,fwh"
+.sp
If you have multiple supported PCI cards which can program flash chips
(NICs, SATA/IDE controllers, etc.) in your system, you must use the
.B "flashrom -p xxxx=bb:dd.f"
