misc: pci_endpoint_test: Handle 64-bit BARs properly A 64-bit BAR consists of a BAR pair, where the second BAR has the upper bits, so we cannot simply call pci_ioremap_bar() on every single BAR index. The second BAR in a BAR pair will not have the IORESOURCE_MEM resource flag set. Only call ioremap on BARs that have the IORESOURCE_MEM resource flag set. pci 0000:01:00.0: BAR 4: assigned [mem 0xc0300000-0xc031ffff 64bit] pci 0000:01:00.0: BAR 2: assigned [mem 0xc0320000-0xc03203ff 64bit] pci 0000:01:00.0: BAR 0: assigned [mem 0xc0320400-0xc03204ff 64bit] pci-endpoint-test 0000:01:00.0: can't ioremap BAR 1: [??? 0x00000000 flags 0x0] pci-endpoint-test 0000:01:00.0: failed to read BAR1 pci-endpoint-test 0000:01:00.0: can't ioremap BAR 3: [??? 0x00000000 flags 0x0] pci-endpoint-test 0000:01:00.0: failed to read BAR3 pci-endpoint-test 0000:01:00.0: can't ioremap BAR 5: [??? 0x00000000 flags 0x0] pci-endpoint-test 0000:01:00.0: failed to read BAR5 Signed-off-by: Niklas Cassel <niklas.cassel@axis.com> Signed-off-by: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com> Acked-by: Kishon Vijay Abraham I <kishon@ti.com>
