 in BE format (*the relationship is not clearly explained in the v3.0B
 or v3.1B specification*).  However with some care and consideration
 the exact same mapping used for INT and FP regfiles may be applied,

 In OpenPOWER v3.0/1, BF/BT/BA/BB are all 5 bits.  The top 3 bits (0:2)
 select one of the 8 CRs; the bottom 2 bits (3:4) select one of 4 bits
