It's a juno board, so it's not very fast, but I wouldn't
have expected it to hit a 100 second timeout assuming
the test isn't trying to do a ludicrous amount of work.

/ppc64/prom-env/mac99: OK
/ppc64/prom-env/g3beige: OK
/ppc64/prom-env/pseries: OK

real    1m37.657s
user    1m36.748s
sys     0m1.440s

Breaking that down per testcase:

<tmmu/qemu-system-ppc64 tests/prom-env-test -v -p /ppc64/prom-env/mac99
/ppc64/prom-env/mac99: OK

real    0m9.836s
user    0m9.584s
sys     0m0.424s
<u/qemu-system-ppc64 tests/prom-env-test -v -p /ppc64/prom-env/g3beige
/ppc64/prom-env/g3beige: OK

real    0m9.099s
user    0m8.988s
sys     0m0.144s
<qemu-system-ppc64 tests/prom-env-test -v -p /ppc64/prom-env/pseries
/ppc64/prom-env/pseries: OK

real    1m24.362s
user    1m23.572s
sys     0m1.144s

pseries is much slower than the other two and at 85 seconds is
not all that much below the 100s. Something's odd here.
