In linux kernel since version 4.14.326 (release Date: 2023-09-23)  
Enables support for the PCIe controller in the Keystone SoC to
work in endpoint mode. The PCI controller on Keystone is based
on DesignWare hardware and therefore the driver re-uses the
DesignWare core functions to implement the driver.
