This isn't very generic.

I'm guessing some vendors my have quite a few ways to differentiate
between board versions/revisions/cuts etc.

How about another array where a vendor can choose to identify a piece
of hardware however they see fit.

Example 1 (simple version):

/* Version 1 */
opp-version = <1>;

Example 2 (using the kernel's versioning):

/* 2.6.32-rc1 */
opp-version = <2 6 32 1>;

Example 3 (using ST's versioning):

/* Major 2, Minor 0, Cut 2, All substrates */
opp-version = <2 0 2 0xff>;

But how will we parse this with generic code ?

Why would you want to?
