Do we really need these long tables that indicate which bits are used?
As I mentioned before, when I asked for documentation of the format of
these files, all I wanted was a brief not indicating that the data was
binary, and that each bit potentially represents a fuse... Either we
should leave it at that, or actually document what each bit represents,
which would hopefully be a pointless duplication of the TRM.
