Divide ThunderX PCIe driver to general and FDT part - Separate FDT and general PCIe driver parts - Drop some irrelevant printfs that cannot be displayed in FDT attach - Move ranges parsing to FDT portion of PCIe code Obtained from: Semihalf Sponsored by: Cavium Differential Revision: https://reviews.freebsd.org/D5067

Support PEM that is not a PCI endpoint on ThunderX Some chip revisions don't have their external PCIe buses behind the internal bridge. Add support for FDT-configurable PEMs but keep ability for PCIe enumeration.

Add FDT bus capabilities to ThunderX PCI driver New ThunderX firmware incorporates modified DTB that presents different device hierarchy. In the new device tree, MDIO devices are below two additional buses that oddly hang on PCI bridge.

uint32_t range_addr_is_phys(struct pcie_range *, uint64_t, uint64_t);
Improve ThunderX PEM driver to work on pass2 revision Things changed: * do not allocate 4GB of SLI space, because it's the waste of system resources. Allocate only small portions when needed. * provide own implementation of activate_resource which performs address translation between PCI bus and host PA address space. This is temporary solution, should be replaced by bus_map_resource once implemented.

Restore ThunderX Pass1.1 PCI changes removed by r295962 If Enhanced Allocation is not used, we can't allocate any random range. All internal devices have hardcoded place where they can be located within PCI address space. Fortunately, we can read this value from BAR.
