Hmmm, this is quite unexpected.
Can you access to mcbsp2 or 3 registers, or only the mcbsp1 registers are not 
accessible?
One thing that I have noticed is that the McBSP1 (and 3) is under the DSP 
Public Peripherals, while McBSP2 is under MPU Public Peripherals (in 
OMAP1510).
I have to check it further what this actually means...
