New Revision: 1680
URL: http://flashrom.org/trac/flashrom/changeset/1680
Log:
Warn if we skipped all blocks while writing.
Quick hack to print a warning if we skip all blocks in a write
process because they are already equal to the requested image. We
want something like this to make users aware... and some developers
who regularly fall for this too *coughcough*. There might be more
elegant solutions for this... patches welcome.
This does not work for erasing because we do that unconditionally.
