commit dbac5823aee553710b7000edd60dfbd8edecdd47 Author: Stefan Reinauer stefan.reinauer@coreboot.org Date: Tue May 5 16:52:10 2015 -0700
Drop lbtdump, like it's 2007
We have discussed dropping lbtdump since 2007, since it was obsoleted by lxbios (nowadays aka nvramtool) back then.
http://www.coreboot.org/pipermail/coreboot/2007-August/024188.html
Well, it's only eight years later.
