8 | * |
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>. |
