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.
