1 Intel Service Layer Driver for Stratix10 SoC
2 ============================================
3 Intel Stratix10 SoC is composed of a 64 bit qu
4 processor system (HPS) and Secure Device Manag
5 configured from HPS, there needs to be a way f
6 location and size of the configuration data. T
7 configuration data from that location and perf

9 To meet the whole system security needs and su
10 communication with SDM, only the secure world
11 Layer 3) can interface with SDM. All software
12 exception layers must channel through the EL3
13 service from SDM.
14
15 Intel Stratix10 service layer driver, running
16 (EL1, Exception Layer 1), interfaces with the
17 the services for FPGA configuration, QSPI, Cry
18 driver also manages secure monitor call (SMC)
19 code running in EL3.
