CONSTANT:
``BSP_ZERO_WORKSPACE_AUTOMATICALLY``
DATA TYPE:
Boolean feature macro.
RANGE:
Defined or undefined.
DEFAULT VALUE:
This option is BSP specific.
DESCRIPTION:
If ``BSP_ZERO_WORKSPACE_AUTOMATICALLY`` is defined by the BSP and
``CONFIGURE_ZERO_WORKSPACE_AUTOMATICALLY`` is not defined by the
application, then the workspace will be zeroed automatically.
NOTES:
Zeroing memory can add significantly to system boot time. It is not
necessary for RTEMS but is often assumed by support libraries.
