Message:

The hard lock implemented as an addressable register in the configuration interface
of the vci_mem_cache has been removed, as it created a possible live-lock situation.
It should be replaced by an external software queuing lock in case of concurrent access.
This lock was only used by the INVAL and SYNC request for software L2/L3 cache coherence.
The tsar_boot preloader and the giet-vm mmc_driver have been accordingly updated.
