/*  *********************************************************************
    *  Some general notes:
    *
    *  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 SB1250 SOC
    *  manual version 0.2, July 2000.
