This series adds PCIe root port support for the AMD Versal CPM4, CPM5 and QDMA PL (soft IP) host bridges, and enables it along with NVMe storage on the xilinx_versal_virt platform.
Patch 1 adds a generic mmap config-space write helper for host bridges that only decode 32-bit accesses. Patches 2 and 3 add the QDMA PL and CPM4/CPM5 host bridge drivers, respectively. Patch 4 maps the CPM5 ECAM windows as device memory so config space accesses are not cached or reordered. Patch 5 wires everything up in the versal_virt defconfig and adds NVMe as a distro boot target.
