* + initialize the PPC
|
|
* + initialize, configure and realize downstream devices
|
|
* + connect downstream device MemoryRegions to the PPC
|
|
* + realize the PPC
|

* + map the PPC's MemoryRegions to the places in the address map
|
|
* where the downstream devices should appear
|
|
* + wire up the PPC's control lines to the SSE object
|

|
* The PPC mapping differs for the -A and -B1 variants; the -A version

|
|
* all the devices behind that.
