How to expand a parallel port in a coldfire system?

Hi all, I want to expand a standard parallel port in
embedded system 
such as coldfire or other. In a desktop PC, the parallel
port should be 
got from a bridge chip (from PCI to Parallel, PS2 and so
on), and linux 
distribution will support it, but in embedded system, how
can i get a 
standard parallel port? I think:

1: Is there some chips bridge the parallel port from the
local bus of 
coldfire system? If yes, does uClinux support those chips? i
find a 
directory in /uclinux-dist/linux2.4/drivers/parport, this
should be the 
driver of the parport, but how to implement it in hardware?


2: if no, should i use a cpld to implement the ECP protocol
and write 
the driver of linux myself ?

Thanks a lot.

Best regards,

Wicky
