SPCI is renamed as PSA FF-A which stands for Platform Security Architecture Firmware Framework for A class processors. This patch replaces the occurrence of SPCI with PSA FF-A(in documents) or simply FFA(in code). Change-Id: I4ab10adb9ffeef1ff784641dfafd99f515133760 Signed-off-by: J-Alves <joao.alves@arm.com>

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. Signed-off-by: Olivier Deprez <olivier.deprez@arm.com> Change-Id: I35c5abd95c616ae25677302f0b1d0c45c51c042f

As a follow-up to bdd2596d , and related to SPM Dispatcher EL3 component and SPM Core S-EL2/S-EL1 component: update with cosmetic and coding rules changes. In addition: -Add Armv8.4-SecEL2 arch detection helper. -Add an SPMC context (on current core) get helper. -Return more meaningful error return codes. -Remove complexity in few spmd_smc_handler switch-cases. -Remove unused defines and structures from spmd_private.h Signed-off-by: Olivier Deprez <olivier.deprez@arm.com> Change-Id: I99e642450b0dafb19d3218a2f0e2d3107e8ca3fe

This patch introduces the `SPCI_ID_GET` interface which will return the ID of the calling SPCI component. Returns 0 for requests from the non-secure world and the SPCI component ID as specified in the manifest for secure world requests.

Added SPMD_SPM_AT_SEL2 build command line parameter. Set to 1 to run SPM at S-EL2. Set to 0 to run SPM at S-EL1 (pre-v8.4 or S-EL2 is disabled). Removed runtime EL from SPM core manifest.

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.
