Depending on SKU, there are up to four possible lane assignments for root ports 1-4.

Root port configurations are set by SoftStraps stored in SPI flash, and the default 
option is “(4) x1”. Links for each root port will train automatically to the maximum 
possible for each port.

x2 link widths are not common. Most devices will only train to x1 or x4.

PCI functions in PCI configuration space are disabled for root ports not available.
