The PCIe controller of layerscape just have 4 BARs, BAR0 and BAR1 is 32bit, BAR2 and BAR4 is 64bit, this is determined by hardware, so set the bar_fixed_64bit with 0x14. Signed-off-by: Xiaowei Bao <redacted> --- v2: - Replace value 0x14 with a macro. v3: - No change. v4: - send the patch again with '--to'. v5: - fix the commit message. v6: - remove the [EXT] tag of the $SUBJECT in email. drivers/pci/controller/dwc/pci-layerscape-ep.c | 1 + 1 file changed, 1 insertion(+)
