I have pushed the series.
If something breaks I fix that when I return
on next Monday.

I have checked that code does not break build
of below listed targets. State of Cache Manager
operations is included. As for actual compatibility
of operations with cores I think that

  rtems_cache_flush_multiple_data_lines( buf, size );
  rtems_cache_invalidate_multiple_data_lines( buf, size );
  rtems_cache_instruction_sync_after_code_change(code_addr, n_bytes )

should be be OK/compatible for all these targets with
cache_.h file variant selected selected in BSP.
Operations for complete cache flush are not correct
for pre-Cortex targets and are missing mostly.
This would require work in future.
