  44     *  Some general notes:
  45     *
  46     *  This file is basically a "what's new" header file.  Since the
  47     *  BCM1250 and the new BCM1480 (and derivatives) share many common
  48     *  features, this file contains only what's new or changed from
  49     *  the 1250.  (above, you can see that we include the 1250 symbols
  50     *  to get the base functionality).
  51     *
  52     *  In software, be sure to use the correct symbols, particularly
  53     *  for blocks that are different between the two chip families.
  54     *  All BCM1480-specific symbols have _BCM1480_ in their names,
  55     *  and all BCM1250-specific and "base" functions that are common in
  56     *  both chips have no special names (this is for compatibility with
  57     *  older include files).  Therefore, if you're working with the
  58     *  SCD, which is very different on each chip, A_SCD_xxx implies
  59     *  the BCM1250 version and A_BCM1480_SCD_xxx implies the BCM1480
  60     *  version.
