When an EEH error occurs, the device/slot is disconnected. This condition is more reliably detected (i.e., returns all ones) with an MMIO read rather than a config read -- especially on power platforms. Hence, this patch fixes EEH error detection by replacing config reads with MMIO reads for reading the error registers. The error registers in Skyhawk-R/BE2/BE3 are accessible both via the config space and the PCICFG (BAR0) memory space.
