[PATCH v3 0/2] tpm: CRB: Use ram_device for "tpm-crb-cmd" region

[Philippe Mathieu-Daudé]

This is a respin of Eric's work, but not making tpm_crb.c target
specific.

Based-on: <20220120000836.229419-1-f4bug@amsat.org>

Eric's v2 cover:

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.
