z8530_read_port - Architecture specific interface function
int z8530_read_port (unsigned long p);
p port to read
Provided port access methods. The Comtrol SV11 requires no delays
between accesses and uses PC I/O. Some drivers may need a 5uS delay
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
The caller must hold sufficient locks to avoid violating the horrible
5uS delay rule.
