[U-Boot] [PATCH v3 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

Changes in v3:
- Added function to read bar config
- Fixed a bug in set MSI implementation (missing -1)
- Elaborate a bit more in comments
- Added MAINTAINER entry for PCI Endpoint
- Added more description to commit message and kmsg
- Removed some unused functionality that can't be
   tested.
- Removed entries from sandbox config and added implies and select
  to arch/Kconfig sandbox entry.
- Added more testing of sandbox driver

  drivers: pci_ep: Introduce UCLASS_PCI_EP uclass
  pci_ep: add Cadence PCIe endpoint driver
  pci_ep: add pci endpoint sandbox driver
  test: pci_ep: add basic pci_ep tests
