[PATCH 0/5] Update GRLIB L2C driver for technical note TN-0021

[Sebastian Huber]

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?
