HAB Access from rootfs

Hello,

is it possible to access the HAB from initramfs/rootfs? Or the last stage to access it from is the U-Boot?

Thanks,

Aleksandar

App note AN12263 (HABv4 RVT Guidelines and Recommendations) describes
API, which is provided by the on-chip ROM, that allows the use of the HAB library
to extend the root of trust and authenticate additional software images.

We do not have Linux support for this API.

Yuri.
