Jeffrey Hugo f8d0c6d199 accel/qaic: Implement quirk for SOC_HW_VERSION ... [ Upstream commit 4c8874c2a6 ] The SOC_HW_VERSION register in the BHI space is not correctly initialized by the device and in many cases contains uninitialized data. The register could contain 0xFFFFFFFF which is a special value to indicate a link error in PCIe, therefore if observed, we could incorrectly think the device is down. Intercept reads for this register, and provide the correct value - every production instance would read 0x60110200 if the device was operating as intended.
