tsar_generic_iob:

• Replacing "ad-hoc" dspin_tsar router by standard dspin_router on the RAM interconnect. To do so, in IO clusters (clusters with IOB) two crossbars are implemented:

+ One for commands which interconnects MEMC and IOB to the

local interface of RAM CMD dspin_router.

+ One for responses which interconnects local interface of RAM

RSP dspin_router to MEMC and IOB.

• Introducing modified vci_io_bridge component

• Modifying IOX memory segments used by IOX network for routing:

+ bugfix: all segments of IOX interconnect must have

global id = 0.

+ Adding XICU segments with special attribute. This

attribute is used by IOB to determine if a command coming
from external DMA peripheral should be routed
through INT or RAM networks.

+ Using bit 32 of physical address to determine if an

external DMA command should be routed through IOB0
or IOB1.
