Unnecessary parens. Why do we need GET_SVR(), versus opencoding it? Note that U-Boot (which this is patterned after) doesn't have GET_SVR(), so code that wants to work on both can't use it anyway.

I don't think IS_SVR_REV is needed. Callers can just do "if (SVR_REV(svr) == 0x30)" or whatever, especially since we're relying on them to do this for greater/less than comparisons.
