Create a new device to emulate the SK hynix Niagara MHSLD platform.
This device has custom CCI commands that allow for applying isolation
to each memory block between hosts. This enables an early form of

The tests from tests/avocado/migration.py do not work at all
on s390x - the bios shuts down immediately when it cannot find

already do such tests in the migration *qtest*

In system mode, abi_ptr is primarily used for representing addresses
when accessing guest memory with cpu_[st|ld]*(). Widening it from
target_ulong to vaddr reduces the target dependence of these functions
and is step towards building accel/ once for system mode.

In order to use virtio backends we need to initialize RAM for the
xen-mapcache (which is responsible for mapping guest memory using foreign
mapping) to work. Calculate and add hi/low memory regions based on
machine->ram_size.

In order to use virtio backends we need to allocate virtio-mmio
parameters (irq and base) and register corresponding buses.
Use the constants defined in public header arch-arm.h to be
aligned with the toolstack. So the number of current supported
virtio-mmio devices is
Since Linux commit 00f918f61c56 ("RISC-V: KVM: Skeletal in-kernel AIA
irqchip support") checking KVM_CAP_IRQCHIP returns non-zero when the
RISC-V platform has AIA. The cap indicates KVM supports at least one
of the following ioctls:

kvm_arch_get_default_type() returns the default KVM type. This hook is
particularly useful to derive a KVM type that is valid for "none"

KVM.
For MIPS, the existing mips_kvm_type() is reused. This function ensures
