union/struct representations for MAS Registers

I have some and use them in some code, they represent ISA 2.06 MAVN=3D1 =
(version 2)
Can I keep them?
if so, should I put them somewhere useful to others?

Examples:
union mas1 {
	u32 _val;
	struct {
		u32 v:1;
		u32 iprot:1;
		u32 tid:14;
		u32 _reserved_1:2;
		u32 ind:1;
		u32 ts:1;
		u32 tsize:4;
		u32 _reserved_2:8;
	};
};
