    serial, ns16550: bugfix: ns16550 fifo not enabled · 17fa0326

    commit: 65f83802 "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
    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:
