NAME

6       z8530_write_port - Architecture specific interface function
7

SYNOPSIS

9       void z8530_write_port(unsigned long p, u8 d);
10

ARGUMENTS

12       p
13           port to write
14
15       d
16           value to write
17

DESCRIPTION

19       Write a value to a port with delays if need be. Note that the caller
20       must hold locks to avoid read/writes from other contexts violating the
21       5uS rule
22
23       In the longer term this should become an architecture specific section
24       so that this can become a generic driver interface for all platforms.
25       For now we only handle PC I/O ports with or without the dread 5uS
26       sanity delay.
