Subject: [PATCH 5.6 29/41] serial: 8250: Enable 16550A variants by default on non-x86
Date: Tue,  9 Jun 2020 19:45:31 +0200	[thread overview]
Message-ID: <20200609174114.888204498@linuxfoundation.org> (raw)
In-Reply-To: <20200609174112.129412236@linuxfoundation.org>

From: Josh Triplett <josh@joshtriplett.org>

commit 15a3f03d5ec0118f1e5db3fc1018686e72744e37 upstream.

Some embedded devices still use these serial ports; make sure they're
still enabled by default on architectures more likely to have them, to
avoid rendering someone's console unavailable.

 	  The 8250 driver can probe for many variants of the venerable 16550A
 	  serial port. Doing so takes additional time at boot.
