36  * This file contains definitions for various T4 register value hardware
37  * constants.  The types of values encoded here are predominantly those for
38  * register fields which control "modal" behavior.  For the most part, we do
39  * not include definitions for register fields which are simple numeric
40  * metrics, etc.
41  *
42  * These new "modal values" use a naming convention which matches the
43  * currently existing macros in t4_reg.h.  For register field FOO which would
44  * have S_FOO, M_FOO, V_FOO() and G_FOO() macros, we introduce X_FOO_{MODE}
45  * definitions.  These can be used as V_FOO(X_FOO_MODE) or as (G_FOO(x) ==
46  * X_FOO_MODE).
47  *
48  * Note that this should all be part of t4_regs.h but the toolset used to
49  * generate that file doesn't [yet] have the capability of collecting these
50  * constants.
