flashrom

This can be repro with dummyflasher and the file to write can be any random file.

Example this command:

flashrom -p dummy:emulate=S25FL128L,freq=64mhz --fmap -w random.rom --progress

Running this floods the output with non-stop repeating message Fixing total value of stage 0 progress on the fly. Probably message is shown each time a byte, or a chunk is read from flash.

flashrom reads from flash because it tried to search for fmap there. fmap is not there, but this situation (reading before starting the actual operation?) makes progress very confused.

Just to be clear, fmap functionality works, no problems there. This is a bug with progress indicator in combination with fmap.
