top.cpp @ 247

Last change on this file since 247 was 247, checked in by cfuguet, 12 years ago

Introducing new CLEANUP transaction address specification in the components:

vci_cc_vcache_wrapper_v4
vci_mem_cache_v4

The new specification uses the VCI WDATA and the VCI BE to send the cleanup
nline. The VCI ADDRESS is like follows:

NLINE MSb | Memory Cache local ID | 00....00

The platforms:

tsarv4_mono_mmu
tsarv4_generic_mmu

has been modified to use the modified components and the mapping table for the coherence
address space has been updated.
