Attached is CVS diff against my current tree.
Beside 2 bug fixes (both by me), this includes some enhancements.
If you can't accept these, I will make a patch consists of only bug
fixes.
* Fixed to do write operation when no option but a filename is supplied
* Fixed wrong error report when enabling flash on vt8231
* Changed to report progress every 4KB instead of byte by byte on some chips
(significantly speeds up flashing those chips)
* Added -c option: only specified Flash ROM is probed; this saves
BIOS Savior users from accidentially overwrite the "known good" BIOS
if he/she forgot to toggle the switch.
