This patch series adds support for PCIe controller on rcar to work in endpoint mode, this also extends the epf framework to handle base region for mapping PCI address locally. Note: The cadence/rockchip/designware endpoint drivers are build tested only. root@salvator-x:~# ./pcitest.sh BAR tests BAR0: OKAY BAR1: NOT OKAY BAR2: OKAY BAR3: NOT OKAY BAR4: OKAY BAR5: NOT OKAY Interrupt tests SET IRQ TYPE TO LEGACY: OKAY LEGACY IRQ: OKAY SET IRQ TYPE TO MSI: OKAY MSI1: OKAY MSI2: OKAY MSI3: OKAY MSI4: OKAY MSI5: OKAY MSI6: OKAY MSI7: OKAY MSI8: OKAY MSI9: OKAY MSI10: OKAY MSI11: OKAY MSI12: OKAY MSI13: OKAY MSI14: OKAY MSI15: OKAY MSI16: OKAY MSI17: NOT OKAY MSI18: NOT OKAY MSI19: NOT OKAY MSI20: NOT OKAY MSI21: NOT OKAY MSI22: NOT OKAY MSI23: NOT OKAY MSI24: NOT OKAY MSI25: NOT OKAY MSI26: NOT OKAY MSI27: NOT OKAY MSI28: NOT OKAY MSI29: NOT OKAY MSI30: NOT OKAY MSI31: NOT OKAY MSI32: NOT OKAY Read Tests SET IRQ TYPE TO MSI: OKAY READ ( 1 bytes): OKAY READ ( 1024 bytes): OKAY READ ( 1025 bytes): OKAY READ (1024000 bytes): OKAY READ (1024001 bytes): OKAY Write Tests WRITE ( 1 bytes): OKAY WRITE ( 1024 bytes): OKAY WRITE ( 1025 bytes): OKAY WRITE (1024000 bytes): OKAY WRITE (1024001 bytes): OKAY Copy Tests COPY ( 1 bytes): OKAY COPY ( 1024 bytes): OKAY COPY ( 1025 bytes): OKAY COPY (1024000 bytes): OKAY COPY (1024001 bytes): OKAY Changes for v6: 1] Rebased patches on endpoint branch of https://git.kernel.org/pub/ scm/linux/kernel/git/lpieralisi/pci.git/ 2] Fixed review comments from Shimoda-san a] Made sure defconfig changes were in seprate patch b] Created rcar_pcie_host/rcar_pcie_ep structures c] Added pci-id for R8A774C0 d] Added entry in MAINTAINERS for dt-binding e] Dropped unnecessary braces 3] Added support for msi.
