b240505a15 rocketchip: move memory channel Xbar from coreplex to rocketchip 
We want to keep the banks split in the outer SoC if there is an L3.
Furthermore, each channel might go to different memory subsystems,
like DDR/HMC/Zero, from rocketchip.

020fbe8be9 diplomacy: make config.Parameters available in bundle connect() 
This makes it posisble to use Parameters to control Monitors.
However, we need to make all LazyModules carry Parameters.

aabd17d935 rocketchip: must create bundles within Module scope 
1. Bundles be created after base class Module constructor runs
2. Bundles must be created before Module(...) runs

Solution: pass a bundle constructor to the cake base class

Require the constructor to take a parameter so people don't use it by
accident; they should get a type error.

Consistently name all the cake arguments with an _io, _coreplex, _outer,
so that they don't shadow the base class variables you should be using.

ec2d23b8b7 rocketchip: Bundle-slices need access to the outer LazyModule

from LazyModule diplomacy.

Now you can eat your cake too!

9910c69c67 Move a bunch more things into util package 
A lot of utility code was just being imported willy-nilly from one
package to another. This moves the common code into util to make things
more sensible. The code moved were

 * The AsyncQueue and AsyncDecoupledCrossing from junctions.
 * All of the code in rocket's util.scala
 * The BlackBox asynchronous reset registers from uncore.tilelink2
 * The implicit definitions from uncore.util

201e247f73 Factor coreplex IO connection into separate trait (#350) 
This would allow, for instance, putting the coreplex on a separate clock
domain and crossing the IOs over through asynchronous queues.

The ExampleMultiClockTop* classes are removed since they no longer fit
into the class hierarchy.

a421469754 tilelink2: change adapters to use TLAdapter(params, defaults)(node) 
This API makes it much more readable when you have multiple adapters
combined into a single line. The arguments for each adapter stay
beside the adapter.

For example, this:
  peripheryBus.node := TLWidthWidget(TLBuffer(TLAtomicAutomata()(TLHintHandler(legacy.node))), legacy.tlDataBytes)
becomes this:
  peripheryBus.node := TLWidthWidget(legacy.tlDataBytes)(TLBuffer()(TLAtomicAutomata()(TLHintHandler()(legacy.node))))
