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.

i recompiled libpri, asterisk and dahdi, it works now.

i patched the code:
/*
 * set up the clock controller
 * we have a 24.576MHz crystal, so the PCM clock is 2x the incoming
clock.
 */
	/* b4xxp_setreg8(b4, R_BRG_PCM_CFG, 0x02); */
        b4xxp_setreg8(b4, R_BRG_PCM_CFG, V_PCM_CLK);

	flush_pci();

	udelay(100);				/* wait a bit for clock to settle */
}
