Hello Martin,
I suggest to remove the grlib/l2c cache support and make sure that
everything is available through the RTEMS Cache Manager.

Hello Martin,
we have also the Cache Manager support in
bsps/sparc/leon3/start/cache.c. At least the lock should be shared
between these two implementations to ensure that there is no concurrent
access.
What is the use case for this driver in grlib? Is it used by the Cache
Manager API?
