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>.
