+Subject: [PATCH] MIPS: JZ4740: Add serial support
+
+The JZ4740 UART interface is almost 16550 compatible.
+The UART module needs to be enabled by setting a bit in the FCR register
+and it has support for receive timeout interrupts.  Instead of adding yet
+another machine specific quirk to the 8250 serial driver we provide a
+serial_out implementation which sets the required additional flags.
