This is due to this[1] missing fix which is mentioned as a dependency in
the cover-letter. I have verified the patch series on the beagleplay
with the delta to tispl being the addition of tifsstub-hs and
tifsstub-fs which add a total of ~60KiB to the totalling 1MiB file.

The runtime correctly only loads the tifsstub-gp binary.

It was only beagleplay that did not have these binaries included and the
build/boot works just fine with the addition.

I will make the requested changes in the v2, thanks for the review.
