-BCM53573 seems to be the first series of Northstar family with wireless
-on the chip. The base models are BCM53573-s (A0, A1) and there is also
-BCM47189B0 which seems to be some small modification.
-
-The only problem with these chipsets seems to be watchdog. It's totally
-unavailable on 53573A0 / 53573A1 and preferable PMU watchdog is broken
-on 53573B0 / 53573B1.
