      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

      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.

      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/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.

      juno: Add romlib support · afa5cfea
      Sathees Balya authored 
      

This patch adds support to build a combined BL1
and ROMLIB binary file with the right page
alignment in Juno. When USE_ROMLIB=1 is set for
Juno, it generates the combined file
bl1_romlib.bin which needs to be used instead of
bl1.bin

      SPM: Register Secure Partition priority level with ehf module · 5681b292
      Sughosh Ganu authored 
      

Register a priority level, PLAT_SP_PRI, for secure partition with EL3
exception handling framework(ehf) module.

The secure partition manager(SPM) would raise the core's priority to
PLAT_SP_PRI before entering the secure partition, to protect the core
from getting interrupted while in secure partition.

      Standardise header guards across codebase · c3cf06f1
      Antonio Nino Diaz authored 
      

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

      Deepak Pandey authored 
      

This patch adds support for the N1SDP (NeoVerse N1 System Development
Platform). It is an initial port and additional features are expected
to be added later.

The port includes only BL31 support as the System Control Processor
(SCP) is expected to take the role of primary boatloader

      FVP: Enable PIE for RESET_TO_BL31=1 · fc922ca8
      Soby Mathew authored 
      

This patch enabled PIE for FVP when RESET_TO_BL31=1. The references
to BL31_BASE are replaced by BL31_START as being a symbol exported by
the linker, will create a dynamic relocation entry in .rela.dyn and
hence will be fixed up by dynamic linker at runtime. Also, we disable
RECLAIM_INIT_CODE when PIE is enabled as the init section overlay
creates some static relocations which cannot be handled by the
dynamic linker currently.
