Nvm, I thought you might have zen2 for some reason.  I have the same device
with zen1 X390 and it seems to work fine here:

        intsmb0 pnpinfo vendor=3D0x1022 device=3D0x790b subvendor=3D0x1849
subdevice=3D0xffff class=3D0x0c0500 at slot=3D20 function=3D0 dbsf=3Dpci0:0=
:20:0
handle=3D\_SB_.PCI0.D07C
            ACPI I/O ports:
                0xb00-0xb0f
          smbus0
            jedec_dimm0 at addr=3D0xa2
            jedec_dimm1 at addr=3D0xa6
            jedec_dimm2 at addr=3D0xaa
            jedec_dimm3 at addr=3D0xae

(Different subvendor/subdevice?  Not sure that matters.)  Same I/O port ran=
ge.=20
My SPD addresses are at different locations, but that is expected.

Yeah, it is an old piece of IP, introduced in family 15h model ~70h ("Carri=
zo"
APU, I guess).  They reuse it in Zen.
