Patch Set 11: -Code-Review

Patchset:

PS11: 
Just realized there are multiple bit-vs-bytes issues here (probably also before
the patch).

Numbers in the cmos.layout are in bits. AFAICT, the struct is 10 Bytes long.
The `/ 8` was lost between patchsets, but the length looks wrong from the
beginning.

Checking the alignment might not be necessary because nvramtool should handle
that at build time. But please test to make sure in case you want to remove
the check.
