    Subject[PATCH RFC] serial/8250: Adjusting FIFO parameters for LPC32xx
    Date
    Hi,

    this is how the modified FIFO is handled in the repositories at
    git.lpclinux.com. Is there a better way for doing this (without ifdef)? Looks
    like registering additional types (like PORT_16550A) isn't encouraged. Maybe
    extending of_serial.c? The latter currently doesn't handle .fifosize and
    .tx_loadsz, though.

    Any suggestions appreciated.

    Thanks in advance,

    Roland
