[Qemu-devel] [PATCH 25/71] tests/libqos: arm/sabrelite machine node

[Paolo Bonzini <pbonzini@redhat.com>]

From: Emanuele Giuseppe Esposito <e.emanuelegiuseppe@gmail.com>

Add arm/sabrelite machine to the graph. This machine contains generic-sdhci, so
its constructor must take care of setting it properly when called.
