This series aims at removing a spurious error message we get when
launching a guest with a TPM-CRB device and VFIO-PCI devices.
The CRB command buffer currently is a RAM MemoryRegion and given
its base address alignment, it causes an error report on
vfio_listener_region_add(). This series proposes to use a ram-device
region instead which helps in better assessing the dma map error
failure on VFIO side.

Eric

History:
v3 -> v4:
- Use PRIxPTR
- call vmstate_unregister_ram
v2 -> v3: respin by Philippe to remove meson changes
v1 -> v2:
- added tpm_crb_unrealize (dared to keep Stefan's T-b though)
