[RFC PATCH 0/4] hw/cxl/ + /hw/pci/: PCI DOE + CXL CDAT emulation

[Jonathan Cameron]

Whilst I know others are working on an implementation of at least some of
this, a desire to work on the kernel user of this required an
implementation so I threw this together in the meantime and am sending
it out on the basis that it may be of use to others.

As it is an RFC I have been lazy on some cleanup and error handling.
Will fix that in a future version if we decide to take this forwards.

Based on Ben's cxl-2.0v3 branch from https://gitlab.com/bwidawsk/qemu
Possible I've picked an unstable branch so this may or may not currently
apply :)  I'll rebase on Ben's next version when avaialble.

Jonathan Cameron (4):
  include/standard-headers/linux/pci_regs: temp hack to add necessary
    DOE definitions.
  hw/pci/pcie_doe: Introduce utility functions for PCIe DOE
  hw/cxl/cxl-cdat: Initial CDAT implementation for use by CXL devices
  hw/mem/cxl_type3: Enabled DOE mailbox for access to CDAT
