2020-09-01	75e1dfa Browse files » spmd: remove assert for SPMC PC value ... This patch removes the assert that expects the SPMC PC value to be same as BL32_BASE. This assumption is not true for all platforms e.g. Tegra, and so will be removed from the SPMD. Platforms can always add this check to the platform files, if required.

	f0d743d Browse files » SPMD: handle SPMC message to register secondary core entry point ... Upon booting, the SPMC running on the primary core shall register the secondary core entry points to which a given secondary core being woken up shall jump to into the SPMC . The current implementation assumes the SPMC calls a registering service implemented in the SPMD for each core identified by its MPIDR. This can typically happen in a simple loop implemented in the early SPMC initialization routines by passing each core identifier associated with an entry point address and context information. This service is implemented on top of a more generic SPMC<=>SPMD interface using direct request/response message passing as defined by the FF-A specification.

2020-05-13	23d5ba8 Browse files » SPMD: extract SPMC DTB header size from SPMD ... Currently BL2 passes TOS_FW_CONFIG address and size through registers to BL31. This corresponds to SPMC manifest load address and size. The SPMC manifest is mapped in BL31 by dynamic mapping. This patch removes BL2 changes from generic code (which were enclosed by SPD=spmd) and retrieves SPMC manifest size directly from within SPMD. The SPMC manifest load address is still passed through a register by generic code.

2020-02-10	bdd2596 Browse files » SPMD: add SPM dispatcher based upon SPCI Beta 0 spec ... This patch adds a rudimentary SPM dispatcher component in EL3. It does the following: - Consumes the TOS_FW_CONFIG to determine properties of the SPM core component - Initialises the SPM core component which resides in the BL32 image - Implements a handler for SPCI calls from either security state. Some basic validation is done for each call but in most cases it is simply forwarded as-is to the "other" security state.
