Subject: [PATCH] early_port_register
Date: Thu, 12 Jun 2003 13:20:01 -0700 [thread overview]
Message-ID: <20030612132001.A4693@home.com> (raw)
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.
