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