Well, immr is _already_ part of bd_t passed from U-Boot! I was 
surprised that none of board ports (some of which are made for U-Boot 
only) use this. 

In 8248 based board port I'm working on right now, I already defined 
CPM_MAP_ADDR as follows:

#define CPM_MAP_ADDR            (((bd_t*)__res)->bi_immr_base)
