Now we are developing for different device using pcie-xilinx.c as reference. When we trying to compile our new driver with latest kernel we are getting compilation problems for struct hw_pci and struct pci_sys_data for ARM64. These structures are not defined in ARM64. The following patch has the structure definitions "https://lkml.org/lkml/2014/7/3/764";. We have used this patch and able complete our development. Now for up streaming it we need this patch in main line. From your discursion we understood that some work is going on ARCH independent API and structure. When can we expect them in mainline? -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
