 This table contains the list of errata that are necessary for known
 problems with particular silicon.  The format is vendorID, revisionID,
 lowest revisionID needing errata, highest rev needing errata, errataBits.
 The result of all matches is ORed together, so more than one entry may
 match.  Typically for a given errata a list of chips revisions that
 this applies to is supplied.
