Subject: [PATCH] MAINTAINERS: add self as reviewer to INTEL STRATIX10 FIRMWARE DRIVERS

From: Tom Rix <[email protected]>

The Intel stratix 10 is a fpga. I review fpga's. So I want to help
in this related subsystem.

Intel Stratix10 service layer driver is not a FPGA.

Intel FPGA SoC is composed of ARM Cortex hard processor system (HPS) and
Secure Device Manager (SDM). SDM is the hardware which does FPGA
configuration, remote system update (RSU), crypto service (FCS), warm
reset and other features.

To meet the whole system security needs and support virtual machine
requesting communication with SDM, only the secure world of software
(EL3) can interfaces with SDM. All software entities running on the
other exception level must channel through the EL3 software whenever it
needs service from SDM.

Intel Stratix 10 service layer driver, added into Opensource kernel
mainlines since version 5.0, interfaces with the service provides at EL1
(FPGA manager, RSU and FPGA crypto service drivers as today) and
managers secure monitor call (SMC) to communicate with the secure
monitor software at the secure world (EL3).

Regards,
Richard
