In meantime the support for the Exynos5440 SoCs has been completely dropped from mainline kernel, as those SoCs never reached the market. The PCIe driver for Exynos5440 variant however has not been removed yet. This patchset simply reworks it to support the Exynos5433 variant. The lack of the need to support both variants significantly simplifies the driver code.
