As per the Final production Data Manual for OMAP5432,
SWPS050F(APRIL 2014)
There are only two OPPs - 1GHz and 1.5GHz. the older OPP_LOW has been
completely descoped. The Nominal voltages are still correct though.
However, expectation for final production configuration is operation
with Adaptive Body Bias (ABB) and Adaptive Voltage Scaling Class 0
operation.
There are no IDcode or version change information encoded to
programmatically detect this and software is supposed to NOT use
OPP_LOW(500MHz) anymore for all devices (legacy and production
samples).
