      services: TRNG: Fix -O0 compilation · 323b6c63
      Andre Przywara authored 
      

The code to check for the presence of the TRNG service relies on
toolchain garbage collection, which is not enabled with -O0.

Add #ifdef guards around the call to the TRNG service handler to
cover builds without optimisation as well.

This patch provides the changes listed below:
- Adds new bit fields definitions for SCTLR_EL1/2 registers
- Corrects the name of SCTLR_EL1/2.[20] bit field from
SCTLR_UWXN_BIT to SCTLR_TSCXT_BIT
- Adds FEAT_PANx bit field definitions and their possible
values for ID_AA64MMFR1_EL1 register.
- Adds setting of SCTLR_EL1.SPAN bit to preserve PSTATE.PAN
on taking an exception to EL1 in spm_sp_setup() function
(services\std_svc\spm_mm\spm_mm_setup.c)

      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.

      xlat_tables_v2: add base table section name parameter for spm_mm · 0922e481
      Masahisa Kojima authored 
      Core spm_mm code expects the translation tables are located in the
inner & outer WBWA & shareable memory.
REGISTER_XLAT_CONTEXT2 macro is used to specify the translation
table section in spm_mm.

In the commit 363830df

 (xlat_tables_v2: merge
REGISTER_XLAT_CONTEXT_{FULL_SPEC,RO_BASE_TABLE}), REGISTER_XLAT_CONTEXT2
macro explicitly specifies the base xlat table goes into .bss by default.
This change affects the existing SynQuacer spm_mm implementation.
plat/socionext/synquacer/include/plat.ld.S linker script intends to
locate ".bss.sp_base_xlat_table" into "sp_xlat_table" section,
but this implementation is no longer available.

This patch adds the base table section name parameter for
REGISTER_XLAT_CONTEXT2 so that platform can specify the
inner & outer WBWA & shareable memory for spm_mm base xlat table.
If PLAT_SP_IMAGE_BASE_XLAT_SECTION_NAME is not defined, base xlat table
goes into .bss by default, the result is same as before.

      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.
