From 270237687a7f550e86c01548550f25b1d0a31d65 Mon Sep 17 00:00:00 2001 From: Carl-Daniel Hailfinger Date: Wed, 28 Apr 2010 15:22:14 +0000 Subject: One of the problems is that --force had multiple meanings - Force chip read by faking probe success. - Force chip access even if the chip is bigger than max decode size for the flash bus. - Force erase even if erase is known bad. - Force write even if write is known bad. - Force writing even if cbtable tells us that this is the wrong image for this board. This patch cleans up --force usage: - Remove any suggestions to use --force for probe/read from flashrom output. - Don't talk about "success" or "Found chip" if the chip is forced. - Add a new internal programmer parameter boardmismatch=force. This overrides any mismatch detection from cbtable/image comparisons. - Add a new internal programmer parameter laptop=force_I_want_a_brick. - Adjust the documentation for --force. - Clean up the man page a bit whereever it talks about --force or laptops. Additional changes in this patch: - Add warnings about laptops to the documentation. - Abort if a laptop is detected. Can be overridden with the programmer parameter mentioned above. - Add "Portable" to the list of DMI strings indicating laptops. - Check if a chip specified with -c is known to flashrom. - Programmer parameter reliability and consistency fixes. - More paranoid self-checks. - Improve documentation. Corresponding to flashrom svn r996.
