+ *
+ *     <x>_w(void) : Returns the word offset for word (4 byte) element <x>.
+ *
+ *     <x>_<y>_s(void) : Returns size of field <y> of register <x> in bits.
+ *
+ *     <x>_<y>_f(u32 v) : Returns a value based on 'v' which has been shifted
+ *         and masked to place it at field <y> of register <x>.  This value
+ *         can be |'d with others to produce a full register value for
