I just merged QEMU support into freedom-u-sdk's master branch. It's still a bit rough around the edges, but on a clean build I can "make qemu" and get into a shell with a DHCP lease.

You can use the riscv-qemu branch in freedom-u-sdk. If you do, make sure to unset RISCV environment variable if you have it set (as it needs a specific version of riscv-gnu-toolchain), then run make qemu
and the SDK will build qemu, a buildroot rootfs and linux-kernel, then start it up:
unset RISCV
git clone --recursive https://github.com/sifive/freedom-u-sdk.git
cd freedom-u-sdk
make qemu
If you want SMP support, you'll need a more recent version of QEMU. The default riscv-qemu riscv-next
branch has relatively solid SMP support:
To build an SMP linux-kernel, run menuconfig, enable "Platform Type" -> "Symmetric Multi-Processing"
make ARCH=riscv menuconfig
To enable smp in QEMU, add -smp cpus=4
to the command line.
I've tested SMP kernels in latest qemu using the riscv-linux-4.14
and riscv-linux-4.15
branches.
You can also take a look at the QEMU wiki. I'll add freedom-u-sdk
instructions to the QEMU wiki, no i've figured out how to get it building (you must unset RISCV environment variable).
