flashrom: Move options -s -e to -S -E and -E to -e.

NOTE! This will break all scripts that erase flash chips automatically. But better now than post 1.0. //Peter

However, I would like to remove the call to erase_winbond_fwhub() in write_winbond_fwhub() - this driver and maybe one or two others do this, and it doesn't seem right. Convenient, sure, but not right. Better make -Ewv work then, and apply the swapopts patch for -ewv. :) //Peter

I'm am flashing this chip several times a day. Also enable unlocking which is only needed when running coreboot, that slipped in the original commit and through the original review ;-) So it must be trivial enough.

Sometimes it will incorrectly identify the ROM file that should be written as a coreboot ROM file, and in that case some data from the ROM file will be used incorrectly and typically cause flashrom to crash with a Segmentation fault. > Could you please provide us some comments or proposals on the problem? To confirm that you are also encountering the known bug, you can try running: flashrom -wv myBIOS.rom -V If you see a message similar to this: coreboot last image size (not ROM size) is 1234 bytes. Where 1234 is some nonsense number, it is indeed the known bug. You can disable the heuristic that is used to identify coreboot ROM files by applying the attached patch or changing layout.c manually. Please let us know if it works for you. Thank you for your interest in flashrom! :) //Peter
