| |
Linus, please apply.
This has been discussed in a previous thread originated by David Mosberger. This removed early_serial_setup() in favor of a working early_port_register() call. Many PPC systems rely on this functionality and are currently hacking around it in the PPC devel tree. Last I looked, IA64 still had this in their devel tree too.
