It was originally introduced on 7422 A0 (40nm) and the test chip that preceded it. The production rev of 7422 uses the 7425 die, so "BCM7425" is a good enough answer for our purposes. BCM7420, BCM7400, and other 65nm SoCs had a ServerWorks SATA2 core on an internal PCI-X bus. These ran a modified version of sata_svw.c, and could support QDMA.
