Niklas Cassel bf597574b6 PCI: endpoint: BAR width should not depend on sizeof dma_addr_t ... If a BAR supports 64-bit width or not depends on the hardware, and should thus not depend on sizeof(dma_addr_t). If a certain hardware doesn't support 64-bit BARs, its epc->ops->set_bar() implementation should return -EINVAL when PCI_BASE_ADDRESS_MEM_TYPE_64 is set. We can't change pci_epc_set_bar() to only set PCI_BASE_ADDRESS_MEM_TYPE_64 based on size, since if the user, for some reason, wants to configure a BAR with a 64-bit width, even though the BAR size is less than 4 GB, he should be able to do that. However, since pci-epf-test is simply a test and not an API, we can set PCI_BASE_ADDRESS_MEM_TYPE_64 in pci-epf-test itself only based on size.
