Summary:                    [patch] Support for generic HFC-4S cards
Description: 
A patch to add some basic support of other HFC-4S -based PCI cards (such as
the ones made by Junghanns). 

Status: gets rid of the echo canceller messages when not needed, but still
needs work.

Specifically:
* It adds too broad a range of cards (which also include bero.net cards) 
* The range may include some 2-ports cards, which will probably not work.

Not yet tested to work, though it it is at least configured.

---------------------------------------------------------------------- 
hello, i patched the code and test it under openvox B400P/Junghanns, it
still does not work. dmesg shows:
----------

------------------------------
asterisk console can see the dahdi channels, but when i make calls, there
is no any response from asterisk. 
i add a small patch to detect Openvox B400P in te mode:
nt = ((gpio & (1 << (i + 4))) != 0); please see the details:	
=========================================
static void hfc_init_all_st(struct b4xxp *b4)
{
	int i, gpio, nt;
	struct b4xxp_span *s;

	gpio = b4xxp_getreg8(b4, R_GPI_IN3);

	for (i=0; i < 4; i++) {
		s = &b4->spans[i];
		s->parent = b4;
		s->port = i;

		nt = ((gpio & (1 << (i + 4))) != 0);		/* GPIO=0 = NT mode */
		s->te_mode = !nt;

		dev_info(b4->dev, "Port %d: %s mode\n", i + 1, (nt ? "NT" : "TE"));

		hfc_reset_st(s);
		hfc_start_st(s);
	}
}
========================================================
