spike: identify an ARM64 device that supports fTPM

[mudler]

Is your feature request related to a problem? Please describe.
As part of #3094 we need to have access to an ARM-based device which supports fTPM

Describe the solution you'd like
Identify a set of devices that the team can get their hands on easily

Describe alternatives you've considered
Use emulation, but that is not real life.

Additional context

I bought http://radxa.com/products/orion/o6/ which should be here by february or so. It should support fTPM out of the box, and key management as well

Seems RPI5 is not a good fit: https://trustedfirmware-a.readthedocs.io/en/v2.11/plat/rpi5.html

I sent an email to Radxa to help us identify a suitable device.

Even something like https://system76.com/desktops/thelio-astra-a1-n1/configure which is incredible, doesnt have fTPM and relies into an external plugged in TPM device https://www.newegg.com/asrock-rack-tpm-spi/p/N82E16816775069

wait, isnt fTPM from AMD? Does arm boards also implement it? Or do they rely into a real TPM module like the one linked above? If its hte latter, maybe we could jsut get a board that has a TPM SPI header and add a TPM module and test with that?

seems like even rpi can be used with a tpm module: https://buyzero.de/collections/andere-platinen/products/letstrust-hardware-tpm-trusted-platform-module

we should definitely get one of these ^ to try it out. Nice finding @Itxaka .
