      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.

      SDS: Introduce the sds drivers · 9bedda4a
      Soby Mathew authored 
      

This patch introduces the driver for Shared-Data-Structure (SDS)
framework which will be used for communication between SCP and AP
CPU. The SDS framework is intended to replace the Boot-Over-MHU
(BOM) protocol used currently for the communication

      Split CSS makefile for sp_min on Juno · 0a04c69a
      Soby Mathew authored 
      

This patch factors out common files required for sp_min for all CSS
platforms from the JUNO specific makefile to a the new `css_sp_min.mk`
makefile. This also allows the common build options that affect CSS
platforms to be configured in a central makefile for sp_min.

      juno: Fix bug in plat_get_my_entrypoint · d9b7636e
      Roberto Vargas authored 
      

plat_get_my_entrypoint was branching to juno_do_reset_to_aarch_32_state,
which is not supposed to return, and in case of returning it implemented
an infinite loop. The problem was that plat_get_my_entrypoint was using
"b" instead of "bl", so juno_do_reset_to_aarch_32_state was returning to
the caller of plat_get_my_entrypoint instead of stop the system with a
panic.

To avoid this problem juno_do_reset_to_aarch_32_state was modified to
call directly to plat_panic_handler if it tries to return.

      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.

      ARM platforms: Map TSP only when TSPD is included · 3eb2d672
      Sandrine Bailleux authored 
      

This patch ensures that the ARM_MAP_TSP_SEC_MEM memory region is mapped
in BL2 only if the TSPD has been included in the build. This saves one
entry in the plat_arm_mmap[] array and avoids to map extra memory when
it's not needed.

      Juno: Define PLAT_LOG_LEVEL_ASSERT to LOG_LEVEL_INFO · bea363ad
      Soby Mathew authored 
      

This patch fixes the PLAT_LOG_LEVEL_ASSERT to 40 which corresponds
to LOG_LEVEL_INFO. Having this level of log for assertions means that the
`assert()` will not generate the strings implied in the expression taken
as parameter. This allows to save some memory when Juno is built for
LOG_LEVEL = LOG_LEVEL_VERBOSE and DEBUG = 1.

Fixes ARM-software/tf-issues#511

      FVP: Always assume shifted affinity with MT bit · 8431635b
      Isla Mitchell authored 
      

At present, the MPIDR validation on FVP relies on MT bit set along
with shifted affinities. This currently is additionally dependent
on the FVP model being of variant C. This however should be based
on the presence of MT bit alone.

This patch makes the change to always assume that the affinities
are shifted in the FVP model when MT bit is present.

      norflash: Add full status check · 3bbe34e5
      Roberto Vargas authored 
      

The nor_XXXXX functions may fail due to different reasons, and it
is convenient to do a full check to detect any failure. It is also
a good idea to have a specific function to do a full status check,
because new checks can be added to this function and they will be
incorporated automatically to any function calling it.
