Z8530_WRITE_PORT(9)						Internal Functions					       Z8530_WRITE_PORT(9)

NAME
       z8530_write_port - Architecture specific interface function

SYNOPSIS
       void z8530_write_port(unsigned long p, u8 d);

ARGUMENTS
       p
	   port to write

       d
	   value to write

DESCRIPTION
       Write a value to a port with delays if need be. Note that the caller must hold locks to avoid read/writes from other contexts violating the
       5uS rule

       In the longer term this should become an architecture specific section so that this can become a generic driver interface for all
       platforms. For now we only handle PC I/O ports with or without the dread 5uS sanity delay.
