+    *  Some general notes:
+    *
+    *  Register addresses are grouped by function and follow the order
+    *  of the User Manual.
+    *
+    *  For the most part, when there is more than one peripheral
+    *  of the same type on the SOC, the constants below will be
+    *  offsets from the base of each peripheral.  For example,
+    *  the MAC registers are described as offsets from the first
+    *  MAC register, and there will be a MAC_REGISTER() macro
+    *  to calculate the base address of a given MAC.
+    *
+    *  The information in this file is based on the BCM1X55/BCM1X80
+    *  User Manual, Document 1X55_1X80-UM100-R, 22/12/03.
+    *
+    *  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.

+    *  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.
