Include the GICv2 makefile in STM32MP1 SP_min makefile, and use ${GICV2_SOURCES} instead of taking drivers/arm/gic files directly. Change-Id: Ibcaed5b0bd17f6d8cf200e208c11cc10cd6d2ee5 Signed-off-by: Yann Gautier <yann.gautier@st.com>

This change implements platform services for stm32mp1 to expose clock and reset controllers over SCMI clock and reset domain protocols in sp_min firmware. Requests execution use a fastcall SMC context using a SiP function ID. The setup allows the create SCMI channels by assigning a specific SiP SMC function ID for each channel/agent identifier defined. In this change, stm32mp1 exposes a single channel and hence expects single agent at a time. The input payload in copied in secure memory before the message in passed through the SCMI server drivers. BL32/sp_min is invoked for a single SCMI message processing and always returns with a synchronous response message passed back to the caller agent. This change fixes and updates STM32_COMMON_SIP_NUM_CALLS that was previously wrongly set 4 whereas only 1 SiP SMC function ID was to be counted. STM32_COMMON_SIP_NUM_CALLS is now set to 3 since the 2 added SiP SMC function IDs for SCMI services.

Embed Arch Architecture SMCCC services in stm32mp1 SP_MIN. This service is needed by Linux kernel to setup the SMCCC conduit used by its SCMI SMC transport driver. Change-Id: I454a7ef3048a77ab73fff945e8115b60445d5841 Signed-off-by: Etienne Carriere <etienne.carriere@linaro.org>

STM32MP1 SoC includes peripheral interfaces that can be assigned to the secure world, or that can be opened to the non-secure world. This change introduces the basics of a driver that manages such resources which assignation is done at run time. It currently offers API functions that state whether a service exposed to non-secure world has permission to access a targeted clock or reset controller.

Use ETZPC driver to configure secure aware interfaces to assign them to non-secure world. Sp_min also configures BootROM resources and SYSRAM to assign both to secure world only. Define stm32mp15 SoC identifiers for the platform specific DECPROT instances. Change-Id: I3bec9f47b04bcba3929e4df886ddb1d5ff843089 Signed-off-by: Etienne Carriere <etienne.carriere@st.com>
