Priorities are not "transitive" across aliases; once you use an alias to map a region, the alias's priority counts, not the target region's priority. So the INT_MIN priority for pci-master-abort counts *within the alias*, but the choice between pci-hole and system.flash is only affected by the priorities of pci-hole and system.flash. You could give a smaller priority (-1 or INT_MIN) to pci-hole and just let it occupy the whole address space, from 0 to UINT64_MAX. Or perhaps the pci-hole alias is too large and it should end before the system flash area. Both solutions should work. Paolo
