In case this configuration option is defined, then the memory areas used for
the RTEMS Workspace and the C Program Heap are zeroed with a ``0x00`` byte
pattern during system initialization.

notes: |
Zeroing memory can add significantly to the system initialization time. It is
not necessary for RTEMS but is often assumed by support libraries. In case
${dirty-memory:/name} is also defined, then the memory is first
dirtied and then zeroed.
