+
+         It is recommended to disable it, when CONFIG_SYS_MALLOC_LEN
+         value, has more than few MiB, e.g. when uses bzip2 or bmp logo.
+         Then the boot time can be significantly reduced.
+         Warning:
+         When disabling this, please check if malloc calls, maybe
+         should be replaced by calloc - if expects zeroed memory.
