To allow bigger 64 bit prefetchable PCI regions in Linux, this patch changes the base address and range of the ACPI area passed to Linux. BayTrail can only physically access 36 bit of PCI address space. So just chaning the range without changing the base address won't work here, as 0xf.ffff.ffff is already the maximum address. With this patch, a maximum of 16 GiB of local DDR is supported. This should be enough for all BayTrail boards though.
