Thank you Peter for pointing me to the right direction. I guess what I need is described here: https://qemu.readthedocs.io/en/latest/specs/tpm.html
Thank you a lot !

Hi there,
I am playing around with qemu arm image of UBoot, and I'm trying to
figure
out how much of UEFI work actually works.
I don't currently have any real arm machine I could use for that, so I chose qemu. In any case, I have mostly followed the following article:
https://www.linaro.org/blog/enabling-uefi-secure-boot-on-u-boot/
I've successfully gotten to setting up EFI variables, but have been
bounced
off by the error:
Missing TPMv2 device for EFI_TCG_PROTOCOL Missing RNG device for EFI_RNG_PROTOCOL
I've glanced through .config and I can see everything TPMv2 and RNG enabled, hence it should be included into Uboot image.
Am I missing something ?
I think you need to ensure you provide the virtual HW from qemu, in the case of the TPM2 you may need to setup swtpm [1]. If you're using something like libvirt or virtmanager to manage the qemu config there's options there to configure those automatically.
