z8530_write_port — Architecture specific interface function


void z8530_write_port (unsigned long p,
 u8 d);


unsigned long p

port to write

u8 d

value to write


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.
