Data Cache
The line-allocate command will not operate on the mini Data Cache, so system software must clean
this cache by reading 2KByte of contiguous unused data into it. This data must be unused and
reserved for this purpose so that it will not already be in the cache. It must reside in a page that is
marked as mini Data Cache cacheable (see Section 2.3.2).
The time it takes to execute the global clean operation depends on the number of dirty lines in the
cache.
