I don't think splitting up makes sense. The one big commit instantiates the ac ranges on the HJSON (5 lines or so) and this triggers ipgen to copy over the IP. If we split it up, there would be inconsistent IPs |

@rswarbrick @vogelpi Since #25894 is merged, this now correctly maps the AC ranges. Can you take another look? |

This adds a base address translation (BAT) on the muxed host TLUL port before exiting to the AC ranges. This BAT removes the 1-2GB offset and downlifsts the address to 0-1GB when exiting. Signed-off-by: Robert Schilling <[email protected]>

This PR instantiates the AC ranges for a single egress port. All Egress ports are muxed to a single egress port before leaving Darjeeling. An additional external miscellaneous port is added to the system that is coming from the external uncore but muxed with same mux and going through the AC ranges.
