Marvell Armada 3700 Functional Specifications, section 52.2 PCIe Link Initialization says that TXDCLK_2X_SEL bit needs to be enabled for PCIe Root Complex mode. Same change was included in TF-A project: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/9408 Signed-off-by: Pali Rohár <pali@kernel.org> Reviewed-by: Stefan Roese <sr@denx.de>
