In case you missed it, Hugo Landau in December appeared at the 37th Chaos Communication Congress (37C3) to talk about how the Broadcom BCM5719 was freed in our favourite OpenPOWER systems. Sure, he's got lots of information on his blog, and you can look at the firmware written to his spec by Evan Lojewski, but there's nothing like hearing him explain the process of how he got it all open (and your jaw dropping to hear that the firmware never checks the signature). It's a good hero story but also reinforces the standard principles of how to make hardware your own, including hardware not particularly amenable to subversion. And Broadcom's a good example of that, by golly. Thanks to Jeremy Rand for the tip.
