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 (12):
PCI: endpoint: BAR width should not depend on sizeof dma_addr_t
PCI: endpoint: Simplify epc->ops->set_bar()/pci_epc_set_bar()
PCI: endpoint: Setting BAR_5 to 64-bits wide is invalid
PCI: endpoint: Setting 64-bit/prefetch bit is invalid when IO is set
PCI: endpoint: Setting a BAR size > 4 GB is invalid if 64-bit flag is
not set
PCI: designware-ep: Make dw_pcie_ep_set_bar() handle 64-bit BARs
properly
PCI: cadence: Set PCI_BASE_ADDRESS_MEM_TYPE_64 if a 64-bit BAR was
set-up
PCI: endpoint: Handle 64-bit BARs properly
PCI: endpoint: Make epc->ops->clear_bar()/pci_epc_clear_bar() take
struct *epf_bar
PCI: endpoint: Make sure that BAR_5 does not have 64-bit flag set when
clearing
PCI: designware-ep: Make dw_pcie_ep_reset_bar() handle 64-bit BARs
properly
misc: pci_endpoint_test: Handle 64-bit BARs properly
