    Shouldn't the first poll option be ARM (with TrustZone [arm.com])?

    I don't know if there are ARM models in use without TrustZone. So I just didn't care.

    Really, I would love the ability to have more than 8 poll options, excessive as it may be.

      I'm pretty sure there are models in use without TrustZone as it is not available on the oldest ARM processors. However, I don't know which models do or do not implement it, and my search engine skills are failing to let me find out easily.

      As for more poll options - I would not object. On the other hand, it can be an engaging exercise to construct a poll that fits within the constraints. In any event, they are not exactly rigorous, but they do serve to generate interesting talking points.

      And in fact TrustZone is disabled on ANY ARM processor whose bootstrap doesn't use a signed kernel, last I checked.

      If the stage0 bootloader doesn't authenticate the stage1 bootloader/kernel as authentic to the vendor key then TrustZone is never initialized.

      This is because TrustZone is only truly used for device encryption and media/software company DRM, neither of which is considered trustworthy if the end user has control of it. Bugs in it that allow 3rd parties to exploit it are preferable to end user control, because the end user is the product and financial extraction target, not the customer.
