19 | * Function naming determines intended use: | |
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>. | |
