      Update Foundation, AEM and Cortex Models versions · 99f38f51
      Eleanor Bonnici authored 
      

Trusted Firmware has been tested as part of its CI system against Cortex
and Foundation models in the 11.1 Model release available on
developer.arm.com. Trusted Firmware has also been tested against the
v8.7 AEM model.  This patch updates the user guide documentation to
reflect the version of the Foundation, AEM and Cortex Models that
Trusted Firmware has been tested against.

      plat/arm: Fix BL31_BASE when RESET_TO_BL31=1 · fd5763ea
      Qixiang Xu authored 
      

The value of BL31_BASE currently depends on the size of BL31. This
causes problems in the RESET_TO_BL31 case because the value of
BL31_BASE is used in the model launch parameters, which often changes.

Therefore, this patch fixes BL31_BASE to the middle of Trusted SRAM,
to avoid further model parameter changes in future.

      Implement log framework · 7f56e9a3
      Soby Mathew authored 
      

This patch gives users control over logging messages printed from the C
code using the LOG macros defined in debug.h Users now have the ability
to reduce the log_level at run time using the tf_log_set_max_level()
function. The default prefix string can be defined by platform by
overriding the `plat_log_get_prefix()` platform API which is also
introduced in this patch.

The new log framework results in saving of some RO data. For example,
when BL1 is built for FVP with LOG_LEVEL=LOG_LEVEL_VERBOSE, resulted
in saving 384 bytes of RO data and increase of 8 bytes of RW data. The
framework also adds about 108 bytes of code to the release build of FVP.

Fixes ARM-software/tf-issues#462

      CSS: Changes for SDS framework · 18e279eb
      Soby Mathew authored 
      

This patch does the required changes to enable CSS platforms
to build and use the SDS framework. Since SDS is always coupled with
SCMI protocol, the preexisting SCMI build flag is now renamed to
`CSS_USE_SCMI_SDS_DRIVER` which will enable both SCMI and SDS on
CSS platforms. Also some of the workarounds applied for SCMI are
now removed with SDS in place.

      cert_tool: Support for legacy RSA PKCS#1 v1.5 · a8eb286a
      Soby Mathew authored 
      

This patch enables choice of RSA version at run time to be used for
generating signatures by the cert_tool. The RSA PSS as defined in
PKCS#1 v2.1 becomes the default version and this patch enables to specify
the RSA PKCS#1 v1.5 algorithm to `cert_create` through the command line
-a option. Also, the build option `KEY_ALG` can be used to pass this
option from the build system. Please note that RSA PSS is mandated
by Trusted Board Boot requirements (TBBR) and legacy RSA support is
being added for compatibility reasons.

      Export KEY_ALG as a user build option · 2091755c
      Soby Mathew authored 
      

The `KEY_ALG` variable is used to select the algorithm for key
generation by `cert_create` tool for signing the certificates. This
variable was previously undocumented and did not have a global default
value. This patch corrects this and also adds changes to derive the
value of `TF_MBEDTLS_KEY_ALG` based on `KEY_ALG` if it not set by the
platform. The corresponding assignment of these variables are also now
removed from the `arm_common.mk` makefile.

      Add usage note for FVP model versions 11.0 and 8.5 · 279fedc1
      David Cunado authored 
      

The internal synchronisation timings of the FVP model version
11.0 build 11.0.34 and version 8.5 build 0.8.5202 has been
changed compared to older version of the models.

This change may have an impact on how the model behaves depending
on the workload being run on the model. For example test failures
have been seen where the primary core has powered on a secondary
core but was then starved of host CPU time and so was not able to
update power status, resulting a test failure due to an incorrect
status. This, or similar behaviour, is not to be expected from
real hardware platforms.

This patch adds a usage note on how to launch these models so
that internal synchronisation timing matches that of the older
version of the models, specifically adding the -Q 100 option.

      bl32: add secure interrupt handling in AArch32 sp_min · 71816096
      Etienne Carriere authored 
      

Add support for a minimal secure interrupt service in sp_min for
the AArch32 implementation. Hard code that only FIQs are handled.

Introduce bolean build directive SP_MIN_WITH_SECURE_FIQ to enable
FIQ handling from SP_MIN.

Configure SCR[FIQ] and SCR[FW] from generic code for both cold and
warm boots to handle FIQ in secure state from monitor.

Since SP_MIN architecture, FIQ are always trapped when system executes
in non secure state. Hence discard relay of the secure/non-secure
state in the FIQ handler.

      CCI: Adapt for specific product at run time · e33fd445
      Jeenu Viswambharan authored 
      

The current build system and driver requires the CCI product to be
specified at build time. The device constraints can be determined at run
time from its ID registers, obviating the need for specifying them
ahead.

This patch adds changes to identify and validate CCI at run time. Some
global variables are renamed to be in line with the rest of the code
base.

The build option ARM_CCI_PRODUCT_ID is now removed, and user guide is
updated.

      FVP: Add support for multi-threaded CPUs · 11ad8f20
      Jeenu Viswambharan authored 
      

ARM CPUs with multi-threading implementation has more than one
Processing Element in a single physical CPU. Such an implementation will
reflect the following changes in the MPIDR register:

  - The MT bit set;

  - Affinity levels pertaining to cluster and CPUs occupy one level
    higher than in a single-threaded implementation, and the lowest
    affinity level pertains to hardware threads. MPIDR affinity level
    fields essentially appear shifted to left than otherwise.

The FVP port henceforth assumes that both properties above to be
concomitant on a given FVP platform.

To accommodate for varied MPIDR formats at run time, this patch
re-implements the FVP platform-specific functions that translates MPIDR
values to a linear indices, along with required validation. The same
treatment is applied for GICv3 MPIDR hashing function as well.

An FVP-specific build option FVP_MAX_PE_PER_CPU is introduced which
specifies the maximum number of threads implemented per CPU. For
backwards compatibility, its value defaults to 1.

This patch adds an early suspend handler, that executes with
SMP and data cache enabled. This handler allows platforms to
perform any early actions during the CPU suspend entry sequence.

This handler is optional and platforms can choose to implement it
depending on their needs. The `pwr_domain_suspend` handler still
exists and platforms can keep on using it without any side effects.

      Emphasize that TF only supports 4 KB granule size · de3d704d
      Sandrine Bailleux authored 
      

At the moment, various parts of the Trusted Firmware code assume
that the granule size used is 4 KB. For example, the linker scripts
enforce 4 KB alignment restrictions on some sections.

However, the ARMv8-A architecture allows 16 KB and 64 KB granule
sizes as well. Some other parts of the TF code, particularly the
architectural code and definitions, have been implemented with
this in mind and cater for all 3 cases.

This discrepancy creates some confusion as to what is effectively
supported in TF. This patch adds some code comments and clarification
in the documentation to make this limitation clearer.
