      plat/arm: Save BL2 descriptors to reserved memory. · 5b8d50e4
      Sathees Balya authored 
      

On ARM platforms, the BL2 memory can be overlaid by BL31/BL32. The memory
descriptors describing the list of executable images are created in BL2
R/W memory, which could be possibly corrupted later on by BL31/BL32 due
to overlay. This patch creates a reserved location in SRAM for these
descriptors and are copied over by BL2 before handing over to next BL
image.

Also this patch increases the PLAT_ARM_MAX_BL2_SIZE for juno when TBBR
is enabled.

Fixes ARM-Software/tf-issues#626

Corrects typos in core code, documentation files, drivers, Arm
platforms and services.

None of the corrections affect code; changes are limited to comments
and other documentation.

      plat/arm: Fix header dependencies · 234bc7f8
      Antonio Nino Diaz authored 
      

From now on, platform_def.h must include any header with definitions that
are platform-specific (like arm_def.h) and the included headers mustn't
include back platform_def.h, and shouldn't be used by other files. Only
platform_def.h should be included in other files. This will ensure that all
needed definitions are present, rather than needing to include all the
headers in all the definitions' headers just in case.

This also prevents problems like cyclic dependencies.

      Move BL1 and BL2 private defines to bl_common.h · c9f9d9ea
      Antonio Nino Diaz authored 
      

The definitions in bl1/bl1_private.h and bl2/bl2_private.h are useful for
platforms that may need to access them.

      Sanitise includes across codebase · 09d40e0e
      Antonio Nino Diaz authored 
      Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca339

 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

      plat/arm: Always define TSP memory region · 07146afb
      Antonio Nino Diaz authored 
      

Even though this is not used unless SPD=tspd, only defining it when
SPD_tspd is defined doesn't have any advantage and it makes it harder to
read the code.

      plat/arm/sgi: Use NT_FW_CONFIG instead of HW_CONFIG · 77ab969a
      Chandni Cherukuri authored 
      

With the two new APIs 'plat_arm_sgi_get_platform_id' and
'plat_arm_sgi_get_config_id' that are available now, BL31 need not
depend on hw_config device tree to identify the platform. In addition
to this, the existing hardware description in hw_config can be limited
to use by BL33 and not by the operating system.

So the hardware description from hw_config dts can be moved into
nt_fw_config dts and the use of hw_config dts can be removed.

      plat/arm/sgi: Use platform specific functions to get platform ids · 699223a2
      Chandni Cherukuri authored 
      

Add two new functions 'plat_arm_sgi_get_platform_id' and
'plat_arm_sgi_get_config_id' which will be implemented by all the
SGI platforms. These functions can be used to determine the part
number and configuration id of the SGI platforms.

In BL2, these functions are used to populate the 'system-id' node.
In BL31, these functions are used to populate the 'sgi_plat_info_t'
structure with the part number and configuration id of the platform.

      Synchronise arch.h and arch_helpers.h with TF-A-Tests · 932b3ae2
      Antonio Nino Diaz authored 
      

The headers forked at some point in the past and have diverged a lot. In
order to make it easier to share code between TF-A-Tests and TF-A, this
patch synchronises most of the definitions in the mentioned headers.

This is not a complete sync, it has to be followed by more cleanup.

This patch also removes the read helpers for the AArch32 instructions
ats1cpr and ats1hr (they are write-only).
