   9   *     <x>_r(void) : Returns the offset for register <x>.
  10   *
  11   *     <x>_w(void) : Returns the word offset for word (4 byte) element <x>.
  12   *
  13   *     <x>_<y>_s(void) : Returns size of field <y> of register <x> in bits.
  14   *
  15   *     <x>_<y>_f(u32 v) : Returns a value based on 'v' which has been shifted
  16   *         and masked to place it at field <y> of register <x>.  This value
  17   *         can be |'d with others to produce a full register value for
  18   *         register <x>.
  19   *
  20   *     <x>_<y>_m(void) : Returns a mask for field <y> of register <x>.  This
  21   *         value can be ~'d and then &'d to clear the value of field <y> for
  22   *         register <x>.
  23   *
  24   *     <x>_<y>_<z>_f(void) : Returns the constant value <z> after being shifted
  25   *         to place it at field <y> of register <x>.  This value can be |'d
  26   *         with others to produce a full register value for <x>.
  27   *
  28   *     <x>_<y>_v(u32 r) : Returns the value of field <y> from a full register
  29   *         <x> value 'r' after being shifted to place its LSB at bit 0.
  30   *         This value is suitable for direct comparison with other unshifted
  31   *         values appropriate for use in field <y> of register <x>.
  32   *
  33   *     <x>_<y>_<z>_v(void) : Returns the constant value for <z> defined for
  34   *         field <y> of register <x>.  This value is suitable for direct
  35   *         comparison with unshifted values appropriate for use in field <y>
  36   *         of register <x>.
