Heiko Schocher 17fa032671 serial, ns16550: bugfix: ns16550 fifo not enabled
commit: 65f83802b7 "serial: 16550: Add getfcr accessor"
breaks u-boot commandline working with long commands
sending to the board.

Since the above patch, you have to setup the fcr register.

For board/archs which enable OF_PLATDATA, the new field
fcr in struct ns16550_platdata is not filled with a
default value ...

This leads in not setting up the uarts fifo, which ends
in problems, when you send long commands to u-boots
commandline.

Detected this issue with automated tbot tests on am335x
based shc board.

The error does not popup, if you type commands. You need
to copy&paste a long command to u-boots commandshell
(or send a long command with tbot)

Possible boards/plattforms with problems:
./arch/arm/cpu/arm926ejs/lpc32xx/devices.c
./arch/arm/mach-tegra/board.c
./board/overo/overo.c
./board/quipos/cairo/cairo.c
./board/logicpd/omap3som/omap3logic.c
./board/logicpd/zoom1/zoom1.c
./board/timll/devkit8000/devkit8000.c
./board/lg/sniper/sniper.c
./board/ti/beagle/beagle.c
./drivers/serial/serial_rockchip.c
