CVS commit: src/sys/dev/ic

[Steve Woodford <scw%netbsd.org@localhost>]

Module Name:    src
Committed By:   scw
Date:           Thu Jun  5 13:40:39 UTC 2003

Modified Files:
        src/sys/dev/ic: com.c comreg.h comvar.h

Log Message:
Add support, via a kernel config file option, for the 16550-compatible
com ports found on Intel PXA2x0 processors.

Re-arrange the code which detects the FIFO configuration to defer
printing until _after_ com_fifo is cleared. Some supposedly compatible
chips clear the Tx/Rx FIFOs when this happens, resulting in previous
output being lost.
