      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.

      Enable CnP bit for ARMv8.2 CPUs · 9fce2725
      Isla Mitchell authored 
      

This patch enables the CnP (Common not Private) bit for secure page
tables so that multiple PEs in the same Inner Shareable domain can use
the same translation table entries for a given stage of translation in
a particular translation regime. This only takes effect when ARM
Trusted Firmware is built with ARM_ARCH_MINOR >= 2.

ARM Trusted Firmware Design has been updated to include a description
of this feature usage.

      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.
