      Don't return error information from console_flush · 831b0e98
      Jimmy Brisson authored 
      

And from crash_console_flush.

We ignore the error information return by console_flush in _every_
place where we call it, and casting the return type to void does not
work around the MISRA violation that this causes. Instead, we collect
the error information from the driver (to avoid changing that API), and
don't return it to the caller.

      xlat_tables_v2: add base table section name parameter for spm_mm · 0922e481
      Masahisa Kojima authored 
      Core spm_mm code expects the translation tables are located in the
inner & outer WBWA & shareable memory.
REGISTER_XLAT_CONTEXT2 macro is used to specify the translation
table section in spm_mm.

In the commit 363830df

 (xlat_tables_v2: merge
REGISTER_XLAT_CONTEXT_{FULL_SPEC,RO_BASE_TABLE}), REGISTER_XLAT_CONTEXT2
macro explicitly specifies the base xlat table goes into .bss by default.
This change affects the existing SynQuacer spm_mm implementation.
plat/socionext/synquacer/include/plat.ld.S linker script intends to
locate ".bss.sp_base_xlat_table" into "sp_xlat_table" section,
but this implementation is no longer available.

This patch adds the base table section name parameter for
REGISTER_XLAT_CONTEXT2 so that platform can specify the
inner & outer WBWA & shareable memory for spm_mm base xlat table.
If PLAT_SP_IMAGE_BASE_XLAT_SECTION_NAME is not defined, base xlat table
goes into .bss by default, the result is same as before.

      TF-A GICv3 driver: Introduce makefile · a6ea06f5
      Alexei Fedorov authored 
      

This patch moves all GICv3 driver files into new added
'gicv3.mk' makefile for the benefit of the generic driver
which can evolve in the future without affecting platforms.
The patch adds GICv3 driver configuration flags
'GICV3_IMPL', 'GICV3_IMPL_GIC600_MULTICHIP' and
'GICV3_OVERRIDE_DISTIF_PWR_OPS' described in
'GICv3 driver options' section of 'build-option.rst'
document.

NOTE: Platforms with GICv3 driver need to be modified to
include 'drivers/arm/gic/v3/gicv3.mk' in their makefiles.

      spm-mm: Refactor secure_partition.h and its contents · aeaa225c
      Paul Beesley authored 
      

Before adding any new SPM-related components we should first do
some cleanup around the existing SPM-MM implementation. The aim
is to make sure that any SPM-MM components have names that clearly
indicate that they are MM-related. Otherwise, when adding new SPM
code, it could quickly become confusing as it would be unclear to
which component the code belongs.

The secure_partition.h header is a clear example of this, as the
name is generic so it could easily apply to any SPM-related code,
when it is in fact SPM-MM specific.

This patch renames the file and the two structures defined within
it, and then modifies any references in files that use the header.

      Remove dependency between SPM_MM and ENABLE_SPM build flags · 3f3c341a
      Paul Beesley authored 
      

There are two different implementations of Secure Partition
management in TF-A. One is based on the "Management Mode" (MM)
design, the other is based on the Secure Partition Client Interface
(SPCI) specification. Currently there is a dependency between their
build flags that shouldn't exist, making further development
harder than it should be. This patch removes that
dependency, making the two flags function independently.

Before: ENABLE_SPM=1 is required for using either implementation.
        By default, the SPCI-based implementation is enabled and
        this is overridden if SPM_MM=1.

After: ENABLE_SPM=1 enables the SPCI-based implementation.
       SPM_MM=1 enables the MM-based implementation.
       The two build flags are mutually exclusive.

Note that the name of the ENABLE_SPM flag remains a bit
ambiguous - this will be improved in a subsequent patch. For this
patch the intention was to leave the name as-is so that it is
easier to track the changes that were made.

      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.

      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
