In LinuxBIOS internal structure for resource, We have index member in resource.

So the resource will be count from 0, ....7 or etc, but index member
will point to real BAR position.

I would like to see Kernel has simmliar definintion.
in LinuxBIOS
typedef uint64_t resource_t;
struct resource {
	resource_t base;	/* Base address of the resource */
	resource_t size;	/* Size of the resource */
	resource_t limit;	/* Largest valid value base + size -1 */
	unsigned long flags;	/* Descriptions of the kind of resource */
	unsigned long index;	/* Bus specific per device resource id */
	unsigned char align;	/* Required alignment (log 2) of the resource */
	unsigned char gran;	/* Granularity (log 2) of the resource */
	/* Alignment must be >= the granularity of the resource */
};
