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.
