Modifications in branches/v5/vci_mem_cache:
- Changing name of CC DSPIN ports:
+ p_dspin_in => p_dspin_p2m
+ p_dspin_out => p_dspin_m2p
- Splitting the Update Table in two tables:
+ UPT (Update Table): Stores the MULTI-UPDATE transactions
+ IVT (Invalidate Table): Stores the MULTI/BROADCAST INVALIDATE
transactions
Each table has its own allocator FSM: r_alloc_upt and r_alloc_ivt

Modifications in branches/v5/modules/vci_mem_cache:
- Introducing third port for the CLACK network.
- CLEANUP FSM is no more a CC_SEND FSM client.
- CLEANUP FSM controls directly the p_dspin_clack port

Bugfix in vci_mem_cache:
- Adding missing "strings" for print_trace() function
- Adding alloc_ivt fsm (Invalidate Table) in the
print_trace() function

Merged
/trunk/modules/vci_mem_cache:449 with
/branches/v5/modules/vci_mem_cache:446.
This merge introduces into the branch the last modifications concerning
the VCI memory cache configuration interface

Modifications in branches/v5/modules/vci_cc_vcache_wrapper:
- Renaming FROM_MC DSPIN flits fields in M2P
- Renaming FROM_L1 DSPIN flits fields in P2M
- Renaming CLEANUP_ACK DSPIN flits fields in CLACK

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

modified CC_RECEIVE FSM and CC_CHECK FSM (icache and dcache) for new
version V5

Bugfix in vci_cc_vcache_wrapper:
- In the states DCACHE/ICACHE CC_UPDT the FSM returns to the
state CC_CHECK only when the cc_send_req is occupied.
We must not return to the CC_CHECK state if not ROK of the
DATA FIFO because the counter word counter will be reset.

Modification in vci_cc_vcache_wrapper:
- Optimization in DCACHE/ICACHE CC_CHECK state.
We can handle a CLACK and a CC request if the latter
does a MISS match. This is because the CC request
doing MISS match does not need to access the directory
=-----------------------------------------------------------------------

Modification in vci_cc_vcache_wrapper:
- Optimization in DCACHE/ICACHE CC_CHECK state.
If pending request to CC_SEND, we wait in the CC_CHECK state.
Doing this, during the wait, we can handle incoming CLACK
avoiding any deadlock situation.
The states CC_UPDT and CC_INVAL do not need to test anymore if
there is a pending request to CC_SEND.

Adding tsar_generic_xbar platform in branches/v5/platforms:
- This platform contains a third local crossbar interconnect
for the CLACK network.
- It works only in a monocluster topology
=-----------------------------------------------------------------------

Modification in branches/v5/platforms/tsar_generic_xbar:
- Adding a DSPIN router to the platform to allow the inter-cluster
communication for the CLACK commands.
With this modification, the tsar_generic_xbar platform can be used
for multi-cluster simulations

Modifications in branches/v5 vci_mem_cache:
- Replacing the third router CLACK by a third virtual channel
in the new virtual_dspin_router supporting several virtual
channels.
The third channel has been added in the COMMAND router.
