Subject: sparc32: always register a PROM based early console
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7671fa22af7a8a066663d93117c866672bd211c8;p=mv-sheeva.git

sparc32: always register a PROM based early console

Do not require user to add "-p" to boot arguments to see
early info printed to prom console.

This is similar to the sparc64 functionality - which was added with:
3c62a2d3477ff7725210db57aec3d2806fa10c20 ("[SPARC64]: Always register
a PROM based early console.")
