Subject: [PATCH 2/3] serial: report base_baud after initialization
Date: Fri, 12 Jul 2013 13:07:39 -0700 [thread overview]
Message-ID: <1373659660-31123-2-git-send-email-keescook@chromium.org> (raw)
In-Reply-To: <1373659660-31123-1-git-send-email-keescook@chromium.org>
Some serial ports will not use the standard base baud rate. Report
this after initialization so it might be discovered and used for early
console configuration.
