When disabling this, please check if malloc calls, maybe
should be replaced by calloc - if one expects zeroed memory.

+ Same as SYS_MALLOC_CLEAR_ON_INIT, but for SPL. It's possible to
+ Enable it without SYS_MALLOC_CLEAR_ON_INIT. It's useful for boards
+ that must have particular memory regions zero'ed before first use.
+ If SYS_SPL_MALLOC_START is configured to be in such region, this
+ option should be enabled.
