Not with qemu, at least not yet.

from the exchange, it doesn't look like that is going to be resolved anytime
soon.

Ok, I'll hold back with adding mips/boston to my qemu tests. Too bad.
Hope this is going to be resolved before qemu and/or platform support
for boston falls apart.

Makes me wonder - is there a way to add initrd support for the platform ?
