Patch Set 2:

Nice! I've been wanting to do this for a while since formatting issues are a common problem especially with submissions we get from newcomers (e.g. thru Github). I'll be happy to take a closer look at this later in the week.

The coding style is similar to coreboot, though we have a couple of differences for line length and tables: https://www.flashrom.org/Development_Guidelines#Coding_style

As Edward said we probably need to fix up a lot of stuff that's currently in the tree.
