^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) ---------------------------------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) Some features of the Intel Stratix10 SoC require a level of privilege
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) higher than the kernel is granted. Such secure features include
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) FPGA programming. In terms of the ARMv8 architecture, the kernel runs
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) at Exception Level 1 (EL1), access to the features requires
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) Exception Level 3 (EL3).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) The Intel Stratix10 SoC service layer provides an in kernel API for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) drivers to request access to the secure features. The requests are queued
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) and processed one by one. ARM’s SMCCC is used to pass the execution
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) of the requests on to a secure monitor (EL3).
