Mac BattOrs freezing with red LED stuck on

Project Member Reported by aschulman@chromium.org, Aug 20 2017

Issue description

Several Mac BattOrs have appeared to have gotten wedged during the download step. This is indicated by the red LED being on when the BattOrs were reset.

I have found a few parts of the download step in the firwmware where these sorts of freezes could happen. They are all extremely unlikely, but I think given the strange behavior of the Mac FTDI driver, they make these freezes much more likely.

I have started rewriting those parts of the download code that could end up in infinite loops to instead do a loop with timeout. I am confident that this will resolve the issue.

As far as I know we haven't seen this issue on the waterfall for a few weeks. So I think this should be closed.
