20   *
21   *     <x>_r(void) : Returns the offset for register <x>.
22   *
23   *     <x>_w(void) : Returns the word offset for word (4 byte) element <x>.
24   *
25   *     <x>_<y>_s(void) : Returns size of field <y> of register <x> in bits.
26   *
27   *     <x>_<y>_f(u32 v) : Returns a value based on 'v' which has been shifted
28   *         and masked to place it at field <y> of register <x>.  This value
29   *         can be |'d with others to produce a full register value for
30   *         register <x>.
31   *
32   *     <x>_<y>_m(void) : Returns a mask for field <y> of register <x>.  This
33   *         value can be ~'d and then &'d to clear the value of field <y> for
34   *         register <x>.
35   *
36   *     <x>_<y>_<z>_f(void) : Returns the constant value <z> after being shifted
37   *         to place it at field <y> of register <x>.  This value can be |'d
38   *         with others to produce a full register value for <x>.
39   *
40   *     <x>_<y>_v(u32 r) : Returns the value of field <y> from a full register
41   *         <x> value 'r' after being shifted to place its LSB at bit 0.
42   *         This value is suitable for direct comparison with other unshifted
43   *         values appropriate for use in field <y> of register <x>.
44   *
45   *     <x>_<y>_<z>_v(void) : Returns the constant value for <z> defined for
46   *         field <y> of register <x>.  This value is suitable for direct
47   *         comparison with unshifted values appropriate for use in field <y>
48   *         of register <x>.
