Only one CPU with krogoth branch, massive tracebacks in dmesg

[koenkooi]

I built and flashed an angstrom build yesterday and I get only one cpu:

    linux-linaro-qcomlt_4.4: update with Linaro 16.09 release

    * merged 4.4.23
    * switch to PSCI by default: so it requires the latest bootloader with PSCI
      enabled

This is very likely a firmware issue. This commit is a big change since we
are switching the platform to PSCI firmware.. So you need to update the tz
partition with the latest file from 16.09 bootloader/rescue release.

In 16.09 there are two tz mbn:

1. tz.mbn
2. tz-psci.mbn

Are you stating we should use tz-psci.mbn instead of tz.mbn?

Loading tz-psci.mbn instead of tz.mbn fixes the problem. I now see four cores.
