[PATCH 1/2] habanalabs: fetch security indication from FW
From: Oded Gabbay
Date: Wed Nov 04 2020 - 03:36:41 EST
From: Ofir Bitton <obitton@xxxxxxxxx>
Add support for fetching security indication from FW.
This indication is needed in order to skip unnecessary
initializations done by FW.
Signed-off-by: Ofir Bitton <obitton@xxxxxxxxx>
