commit: 65f83802b7a5b "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
