Yes. Our infrastructure for doing it in a neatly encapsulated
way has been a bit lacking but is getting better. Already in
the tree there is emulation of OMAP1 and OMAP2 and (just landed)
the Samsung Exynos4210.

SystemC support is a completely unrelated question to whether
we emulate SoCs. (We don't have any SystemC support in mainline,
as it happens.)

At the moment the only M3 based boards we support are the
stellaris ones.
