2.3.21.
General Purpose PCI Express 3.0 (V1000 SKUs)
The V1000 processors support a total of x8 GPP lanes (up to Gen 3):
Lane [4:0] is used as COMe PCIe; Lane 4 optionally connected to PCIe Switch
Lane 5 connected to i210, optionally connected to COMe PCIE 5
Lane [7:6] are multiplexed with SATA

Just five Root Ports are supported at the same time; one is used from the Ethernet
controller. 5 x1 configuration is not possible if Ethernet is populated. There are also
dependencies between GPP and GFX configuration.
2.3.22.
General Purpose PCI Express 3.0 (R1000 SKUs)
The R1000 SKU processors support supports 4 or 8 GPP lanes (up to Gen 3), depending of the SKU. R1505G/R1606G
SKUs are supporting 4 GPP lanes (plus x4 Gfx)
Lane [1:0] is used as COMe PCIe;
Lane 4 optionally connected to PCIe Switch
Lane 5 is connected to i210, optionally connected to COMe PCIE 5
Lane [7:6] are working as SATA only at R1000 SKUs.

Lane 5 is connected to i210/i211. It is not allowed to use COMe PCIe Port 4 as x1 Port. If this
Port is used, Ethernet will not work. A different PCIe configuration have to be selected e.g.
Port 4 and Port 5 as a x1 configuration.
