Changeset 446 for branches/v5/modules/vci_cc_vcache_wrapper/caba/source/include/vci_cc_vcache_wrapper.h

Message:

Modifications in vci_cc_vcache_wrapper:

• Merging the states DCACHE/ICACHE_CC_BROADCAST and DCACHE/ICACHE_CC_INVAL. This is because, the BROADCAST INVALIDATE and the MULTICAST INVALIDATE are both acknowledged by a CLEANUP.

• Adding third port for the clack coherence network.

• Renaming the port dspin_in to dspin_m2p and the port dspin_out to dspin_p2m
