One problem is that in coreboot development we care about style
(although there will be disagreement to which degree).
And not just in a formal way (which indent could solve), but I'd rather
not see things like
(BIT31 | BIT30 | BIT29 | .. all the way down to .. | BIT 1 | BIT 0)
in our tree.
While looking terribly enterprisey, it's just terrible.
Intel code, at least as far as it is public and not part of the Linux
kernel, manages to collect all the horrible code standards in a single

"Luckily", Intel being Intel, the boot code is signed, so it's not as
simple as it sounds.

Indeed. There is no need to bloat coreboot by factor 6. I measured.
