[U-Boot] [PATCH v2 0/4] Add Cadence PCIe endpoint driver with new uclass

[Ramon Fried]

This patchset adds support for new uclass, UCLASS_PCI_EP
allowing new set of PCI endpoint drivers.
Included in the patch is also a driver for Cadence PCIe endpoint.

Changes in V2:
- Removed "pci.h: add missing maskbit" as it was already merged
  by Simon.
- Added PCI endpoint sandbox driver
- Added testing for sandbox driver
- Addressed issues raised by Simon in UCLASS_PCI_EP class implementation

Ramon Fried (4):
  drivers: pci_ep: Introduce UCLASS_PCI_EP uclass
  pci_ep: add Cadence PCIe endpoint driver
  pci_ep: add pci_ep sandbox driver
  test: pci_ep: add basic pci_ep tests
