Subject: [PATCH v4 0/5] PCI endpoint 64-bit BAR fixes

PCI endpoint fixes to improve the way 64-bit BARs are handled.


There are still future improvements that could be made:

pci-epf-test.c always allocates space for
6 BARs, even when using 64-bit BARs (which
really only requires us to allocate 3 BARs).

pcitest.sh will print "NOT OKAY" for BAR1,
BAR3, and BAR5 when using 64-bit BARs.
This could probably be improved to say
something like "N/A (64-bit BAR)".

Niklas Cassel (5):
  PCI: endpoint: BAR width should not depend on sizeof dma_addr_t
  PCI: designware-ep: Make dw_pcie_ep_set_bar() handle 64-bit BARs
    properly
  PCI: designware-ep: Make dw_pcie_ep_reset_bar() handle 64-bit BARs
    properly
  PCI: endpoint: Make pci_epc_set_bar() return the BAR width that was
    set-up
  misc: pci_endpoint_test: Handle 64-bit BARs properly
