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.
