It's not 100% compatible, the mdio ports map to different fman ports, but both as are 'corenet generic' boards, I added varisys,CYRUS so it would be detected in corenet_generic.c - support for the 5020 was added by Andy Flemming, I've just tried to copy what he did.

I can add another entry to the table, but do we realy want a separate entry in the table for every supported board rather than using the device tree for similar boards?

It would be nice to get these sorted, the dts files are the last bits to make these fully supported in Linux.

Opps, will be fixed on next version
