Hi Vikash,

Thanks for this new revision. I don't have much to add, apart from
maybe a few suggestions to make it easier to follow the "story" this
series tells:

* Maybe the no_tz member is appearing too early in the series. For the
first two patches, we still only support loading the firmware through
TrustZone. In patch 3 we initialize no_tz properly, but still cannot
boot without TrustZone, which creates a state where the driver could
parse the firmware node, but would still attempt to use TrustZone.
* I feel like patch 1 should be merged into patch 4, since the
function it introduces is not used before patch 4 anyway.

If you agree I can maybe do the v9 of the series to address the two
points mentioned above, unless Stanimir is already happy with the
state?

In any case, this is doing the job, so:
Tested-by: Alexandre Courbot <acourbot@chromium.org>
