46 BCMA bus may have many versions of PCIe core. This driver
47 supports:
48 1) PCIe core working in clientmode
49 2) PCIe Gen 2 clientmode core
50
51 In general PCIe (Gen 2) clientmode core is required on PCIe
52 hosted buses. It's responsible for initialization and basic
53 hardware management.
54 This driver is also prerequisite for a hostmode PCIe core
