Hi,

This series is the result of a long thread with Peter:
https://www.mail-archive.com/qemu-devel@nongnu.org/msg788366.html

AddressSpace are physical address view and shouldn't be using
non-zero base address. The correct way to map a MR used as AS
root is to use a MR alias.

Fix the current incorrect uses, then forbid further use.

Peter Xu (1):
  memory: Make sure root MR won't be added as subregion

Philippe Mathieu-Daudé (4):
  hw/arm/aspeed: Do not directly map ram container onto main address bus
  hw/arm/aspeed: Do not sysbus-map mmio flash region directly, use alias
  hw/pci-host/prep: Remove unuseful memory region mapping
  hw/pci-host/prep: Do not directly map bus-master region onto main bus
