-/*
- *	Comtrol SV11 card driver
- *
- *	This is a slightly odd Z85230 synchronous driver. All you need to
- *	know basically is
- *
- *	Its a genuine Z85230
- *
- *	It supports DMA using two DMA channels in SYNC mode. The driver doesn't
- *	use these facilities
- *	
- *	The control port is at io+1, the data at io+3 and turning off the DMA
- *	is done by writing 0 to io+4
- *
- *	The hardware does the bus handling to avoid the need for delays between
- *	touching control registers.
- *
- *	Port B isn't wired (why - beats me)
- *
- *	Generic HDLC port Copyright (C) 2008 Krzysztof Halasa <khc@pm.waw.pl>
