This patch series adds support for PCIe controller on rcar to work in endpoint mode,
this also extends the epf framework to handle multiple outbound regions.

Note: 
The cadence/rockchip/designware endpoint drivers are build tested only.

Endpoint configuration:
$ cd /sys/kernel/config/pci_ep
$ mkdir functions/pci_epf_test/func1
$ echo 0x1912 > functions/pci_epf_test/func1/vendorid
$ echo 0x002d > functions/pci_epf_test/func1/deviceid
$ echo 32 > functions/pci_epf_test/func1/msi_interrupts
$ ln -s functions/pci_epf_test/func1/ controllers/fe000000.pcie_ep/
$ echo 1 > controllers/fe000000.pcie_ep/start

Host side results:
lspci output:
