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
