      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.

      drivers/console: Link console framework code by default · 985ee0b7
      Julius Werner authored 
      

This patch makes the build system link the console framework code by
default, like it already does with other common libraries (e.g. cache
helpers). This should not make a difference in practice since TF is
linked with --gc-sections, so the linker will garbage collect all
functions and data that are not referenced by any other code. Thus, if a
platform doesn't want to include console code for size reasons and
doesn't make any references to console functions, the code will not be
included in the final binary.

To avoid compatibility issues with older platform ports, only make this
change for the MULTI_CONSOLE_API.

      plat/common/crash_console_helpers.S: Fix MULTI_CONSOLE_API support · 63c52d00
      Julius Werner authored 
      Crash reporting via the default consoles registered by MULTI_CONSOLE_API
has been broken since commit d35cc347

 (Console: Use callee-saved
registers), which was introduced to allow console drivers written in C.
It's not really possible with the current crash reporting framework to
support console drivers in C, however we should make sure that the
existing assembly drivers that do support crash reporting continue to
work through the MULTI_CONSOLE_API.

This patch fixes the problem by creating custom console_putc() and
console_flush() implementations for the crash reporting case that do not
use the stack. Platforms that want to use this feature will have to link
plat/common/aarch64/crash_console_helpers.S explicitly.

Also update the documentation to better reflect the new reality (of this
being an option rather than the expected default for most platforms).

      plat/common: Remove duplication of plat_crash_console functions/stubs · b2f7c9dd
      Julius Werner authored 
      Commit e74afb65 (Deprecate weak crash console functions) deprecated the
default inclusion of weak definitions for plat_crash_console functions
in plat/common/aarch64/platform_helpers.S. The code was later copied out
to plat/common/aarch64/crash_console_helpers.S so platforms can link it
explicitly if they want to. However, since deprecation does not mean
removal, the same code is also still duplicated in platform_helpers.S.

The duplicated code contains both empty stubs for the !MULTI_CONSOLE_API
case, and a real implementation that used to work but was broken by
commit d35cc347

 (Console: Use callee-saved registers) for
MULTI_CONSOLE_API. It's not great to have both of these duplicated in
two files, so this patch splits them up: in platform_helpers.S we'll
only keep the empty stubs (guarded by !ERROR_DEPRECATED), which should
not regress functionality since the MULTI_CONSOLE_API implementation was
already broken anyway. In crash_console_helpers.S, we'll only keep the
MULTI_CONSOLE_API version, which is enough both as an implementation in
itself and as a sample for how to reimplement these functions in a
platform-specific file.

      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.
