+Intel Stratix10 SoC Service Layer
+---------------------------------
+Some features of the Intel Stratix10 SoC require a level of privilege
+higher than the kernel is granted. Such secure features include
+FPGA programming. In terms of the ARMv8 architecture, the kernel runs
+at Exception Level 1 (EL1), access to the features requires
+Exception Level 3 (EL3).
+
+The Intel Stratix10 SoC service layer provides an in kernel API for
+drivers to request access to the secure features. The requests are queued
+and processed one by one. ARM’s SMCCC is used to pass the execution
+of the requests on to a secure monitor (EL3).
