Yes, that's what I wrote above. The base address register mapping the 
mcBsp at a given address would be described in the detailed spec of the 
SoC, the one with all registers.

Indeed, but this does not mean they are mapped the same way. You can 
only tell by looking at the detailed register map of the SoC.
