[PATCH v3 0/5] arm64: Juno: Add support for PCIe on R1 board

Changes in v3 vs v2:
 - Add Documentation files describing the DT bindings for plda,xpressrich3-axi
   and arm,juno-r1-pcie properties.
 - Cosmetic changes in the .dts to bracket range and interrupt-map entries
Changes in v2 vs v1:
 - Add plda as OF vendor prefix
 - Add more specific compatible values to the Juno R1 DT

Juno R1 board has a working PCIe host bridge that can be enabled and
configured by the firmware and made use of by Linux. For UEFI, the
Linaro releases contain firmware that configure the XpressRICH3 host
bridge correctly. For U-Boot based setups, one needs the patchset
posted here[1].

This patchset adds a quirk for setting the correct class to the host
bridge device and the device tree changes that enable PCIe on Juno R1.
We also update the defconfig to enable the generic PCI host bridge driver.

Best regards,
