* <x>_r(void) : Returns the offset for register <x>.
*
* <x>_w(void) : Returns the word offset for word (4 byte) element <x>.
*
* <x>_<y>_s(void) : Returns size of field <y> of register <x> in bits.
*
* <x>_<y>_f(u32 v) : Returns a value based on 'v' which has been shifted
* and masked to place it at field <y> of register <x>. This value
* can be |'d with others to produce a full register value for
* register <x>.
*
* <x>_<y>_m(void) : Returns a mask for field <y> of register <x>. This
* value can be ~'d and then &'d to clear the value of field <y> for
* register <x>.
*
* <x>_<y>_<z>_f(void) : Returns the constant value <z> after being shifted
* to place it at field <y> of register <x>. This value can be |'d
* with others to produce a full register value for <x>.
*
* <x>_<y>_v(u32 r) : Returns the value of field <y> from a full register
* <x> value 'r' after being shifted to place its LSB at bit 0.
* This value is suitable for direct comparison with other unshifted
* values appropriate for use in field <y> of register <x>.
*
* <x>_<y>_<z>_v(void) : Returns the constant value for <z> defined for
* field <y> of register <x>. This value is suitable for direct
* comparison with unshifted values appropriate for use in field <y>
* of register <x>.
