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.
