      SPM: Fix error codes size in SPMD handler · e46b2fd2
      J-Alves authored 
      

FF-A specification states that error codes should be typed int32_t.
SPMD's uses uint64_t for return values, which if assigned with a signed
type would have sign extension, and change the size of the return from
32-bit to 64-bit.

      spmd: Fix signedness comparison warning · 6e4da01f
      Andre Przywara authored 
      

With -Wsign-compare, compilers issue a warning in the SPMD code:
====================
services/std_svc/spmd/spmd_pm.c:35:22: error: comparison of integer
expressions of different signedness: 'int' and 'unsigned int'
[-Werror=sign-compare]
   35 |  if ((id < 0) || (id >= PLATFORM_CORE_COUNT)) {
      |                      ^~
cc1: all warnings being treated as errors
====================

Since we just established that "id" is positive, we can safely cast it
to an unsigned type to make the comparison have matching types.

      spmd: remove assert for SPMC PC value · 75e1dfa0
      Varun Wadekar authored 
      

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.

      J-Alves authored 
      

Change handler of FFA version interface:
- Return SPMD's version if the origin of the call is secure;
- Return SPMC's version if origin is non-secure.

      SPCI is now called PSA FF-A · 662af36d
      J-Alves authored 
      

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).

      SPMD: extract SPMC DTB header size from SPMD · 23d5ba86
      Olivier Deprez authored 
      

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.

      SPMD: add SPM dispatcher based upon SPCI Beta 0 spec · bdd2596d
      Achin Gupta authored 
      

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.
