  1. BSP difference between mpc7447 and mpc7410?

    We plan to develop a board with mpc7447+evb64260,but we only have
    bsp of mpc7410+evb64260.So I wonder how much difference between
    mpc7447 and mpc7410?
    Is there possible to port bsp from 7410+evb64260 to 7447+evb64260?
    I have looked at u-boot source code,it seems no much difference
    between them ,right?
    Hope for reply,thank you very much!

    ==============

    hi,

    even though processors 7410 and 7447 are of same nature, 7447 is
    faster compared to 7410.
    7410 operates at 400-500MHz, whereas 7447 can operate at 667MHz or
    1GHz.
    So verify your operating speed?

    And there may be changes in BSP's romInit.s and sysALib.s for
    initializing processor regisers.
    In case they are same for both processors, there will be not any
    additional changes.

    Thanks,
