Eugene Cohen ce6aec3ea3 ArmPkg: Convert whole-cache InvalidateInstructionCache to just ASSERT
In SVN 18756 ("disallow whole D-cache maintenance operations")
InvalidateInstructionCache was modified to remove the full data cache
clean but left the full instruction cache invalidate. The change was
made to address issues in the set/way clean methodology but the
resulting code could lead someone to a painful debug. If a component
called this function, the proper code would not be flushed to the PoU,
since the intent of this function is not only to invalidate the I-cache
but to provide coherency after code loading / modification. This change
simply places an ASSERT(FALSE) in this function to avoid this hazard.
