Patch Set #13, Line 31: 0xfed80000
For stoney it was 0xfed80a00. Also, I saw when you defined the register accessed through this MMIO it was saying offset to 0xfed80a00.
D14F0 is the SMBus host controller, which has PCI config space and two BARs for SMBus and ASF. AcpiMmio is a fixed region where you can access all three of these: the config space without a config cycle, and the two controllers without needing to read either BAR. In your ST BKDG, look at the first item in the table of PMx04[1]. That's what this is.
On Stoney, 0xfed80000 was for USB legacy registers, did it change?
That doesn't ring a bell, and I don't know how that could be possible. Can you point me to what you're talking about?
