Alex Deucher b48fea52b9 PCI: Mark AMD Navi14 GPU rev 0xc5 ATS as broken ... commit 5e89cd303e upstream. To account for parts of the chip that are "harvested" (disabled) due to silicon flaws, caches on some AMD GPUs must be initialized before ATS is enabled. ATS is normally enabled by the IOMMU driver before the GPU driver loads, so this cache initialization would have to be done in a quirk, but that's too complex to be practical. For Navi14 (device ID 0x7340), this initialization is done by the VBIOS, but apparently some boards went to production with an older VBIOS that doesn't do it. Disable ATS for those boards.
