@ -2554,8 +2554,13 @@ NOTE: This section assumes that your platform is enabling the MULTI_CONSOLE_API
flag in its platform.mk. Not using this flag is deprecated for new platforms.
BL31 implements a crash reporting mechanism which prints the various registers
of the CPU to enable quick crash analysis and debugging. By default, the
definitions in ``plat/common/aarch64/platform\_helpers.S`` will cause the crash
of the CPU to enable quick crash analysis and debugging. This mechanism relies
on the platform implementating ``plat_crash_console_init``,
``plat_crash_console_putc`` and ``plat_crash_console_flush``.
The file ``plat/common/aarch64/crash_console_helpers.S`` contains sample
implementation of all of them. Platforms may include this file to their
makefiles in order to benefit from them. By default, they will cause the crash
output to be routed over the normal console infrastructure and get printed on
consoles configured to output in crash state. ``console_set_scope()`` can be
used to control whether a console is used for crash output.

platform code. They are executed outside of a C environment and without a stack.

If this behaviour is not desirable, the platform may implement functions that
redirect the prints to the console driver (``console_xxx_core_init``, etc). Most
platforms (including Arm platforms) do this and they can be used as an example.
