Have you got more info on the whole product like name/symbol?

The MV6446x device you mention does not include a SATA block in it. It  
is a system controller (for PowerPC), which indeed has a number of  
peripherals integrated (DDR controler, PIC, PCI/PCIE, Ethernet, XOR  
etc.), but SATA is not one of them. There must be somewhere a separate  
SATA controller on your device besides this one. My speculation is  
that it probably sits behind the MV6446x PCI/PCIE bridge, and since  
there isn't a driver for this PCI/PCIE bridge in the first place, you  
don't see other peripheral(s)...
