        Set minimum running RDP level.
        RDP0 is full debug permissions, RDP1 disables read from Flash but
        otherwise leaves debug enabled, RDP2 disables JTAG completely. If
        there is a mismatch between desired RDP level here and RDP level
        set on the chip, early cpu init will hang.  This ensures production
        devices with the wrong RDP level, by fault or malace intent, will
        not run.  See cpu manual for further details on RDP.
