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
