ARM TrustZone in BB?

ARM Cortex A8 has TrustZone. TrustZone is similar to Trusted Platform Module (TPM). Among uses is digital rights management. See http://mobile.arm.com/products/processors/technologies/trustzone.php?tab=Why+TrustZone?

BB xM has a Cortex A8 DM3730CBP DaVinci processor. The BeagleBone uses a TI AM3358 ARM Cortex-A8. Cortex A8 has Arm TrustZone. Do BB-xM and BeagleBone have TrustZone?

Original BB has a Texas Instrument’s OMAP3350DCBB72 processor. Does have an ARM Cortex? If so, what version? Does it have TrustZone?

Because privacy is important to me, I need a board that does not have TrustZone.

That page says:

"ARM TrustZone technology is an integral feature of all Cortex-A class
processors"

Original Beagle is OMAP3530.
OMAP3530 is Cortex-A8 based.

Trustzone is just as set of hardware features and needs SW to operate it.
This SW is not public and actually costs quite some money to licence.
And in order to uniquely identify you, it is not needed as we already
told you.

Again, it all boils down to whether you *trust* the SW you are running,
regardless of hardware features of the board/computer you are using.
