I finally did what I should have already done before: learned about 
dynamic debugging, turned it on and probably got the answer from 
omap_msbsp_dump_reg(): all mcbsp1 register read operations returned 
0xffff. So it looks like I simply get no acccess to mcbsp1 at all. Now I 
wonder if I can close this thread with a conclusion that mcbsp1 on 
opam15xx is simply not yet supported by the mainline kernel that I have 
based my work on.
