In my old version (2006R2), I had to make modifications in include/asm/cplbtab.h in order to be able to access hardware directly from userspace. I'm wondering whether I have to do that too in the 2009R1 version ? And if so, where to find the file to modify ? (or can I make modifications through kernel config ?)

You need to be able to read/write the async banks? or something else?

I have to access, from user space, some registers that are mapped in the async bank 2 memory region (i.e. above 0x28000000).

Have a look in arch/blackfin/kernel/cplb-nompu/cplbinit.c and arch/blackfin/include/asm/cplb.h
