[Qemu-devel] [PATCH V4 0/6] pxb: fix 64-bit MMIO allocation

[Marcel Apfelbaum <marcel@redhat.com>]

64-bit BARs allocations fix for devices behind PXBs/PXB-PCIEs.

In build_crs() the calculation and merging of the ranges already happens
in 64-bit, but the entry boundaries are silently truncated to 32-bit in the
call to aml_dword_memory(). Fix it by handling the 64-bit MMIO ranges separately.

v3 -> v4:
 Addressed Igor's comments (thanks for the productive review!)
 - Split pxb test patch (previously patch 3/3) into the test itself (patch 1/6) and the blobs (patch 6/6).
 - New patch declaring pxb/pxb-pxie as not hot-pluggable.
    - Note that it does not solve the DSDT issue, but it is a prerequisite for the next patch.
 - New patch solving the DSDT issue spotted by Igor.
     - Using V=1 DIFF=diff make check does make it easier to review the ACPI changes, thanks.
 - Patches 4 and 5 untouched (previously patches 1/3 and 2/3) 

v2 -> v3:
 - split original series "pci: better support for 64-bit MMIO allocation" into 2 series:
    - this is the first part dealing with correct 64-bit MMIO ACPI computation
    - the second one will include 64-bit MMIO reservation for PCI hotplug
 - Add pxb/pxb-pcie tests (Igor) - See diffs below (*)
 - Re-based on latest master.
   
v1 -> v2:
 - resolved some styling issues (Laszlo)
 - rebase on latest master (Laszlo)

Thank you,
Marcel
