52bb6cd9d9 Configs: use a uniform syntax without Match exceptions (#507) 
* Configs: use a uniform syntax without Match exceptions

The old style of specifying Configs used total functions.  The only way to
indicate that a key was not matched was to throw an exception.  Not only was
this a performance concern, but it also caused confusing error messages
whenever you had a match failure from a lookup within a lookup.  The
exception could get handled by an outer-lookup that then reported the wrong
key as missing.

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.

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

ea9f0a868f TileLink utility objects should not take implicit parameters 
We have a handful of TileLink-related helper objects
(wrappers, unwrappers, width adapters, and enqueuers). Previously, using
them could be error-prone, because you had to make sure the implicit
parameters they took in had the same TLId as the TileLinkIO bundles
passed in as inputs. This is rather silly, we should just use the
parameters in the bundle.

14cd39e045 rocketchip: rename identically names devices with _%d (#340) 
* rocketchip: rename identically names devices with _%d

If you connect two devices with the same name in TL2 (totally ok there),
when they get put into the TL1 addrmap, one gets silently overwritten.
This renames the second occurance as _1, third as _2, and so on...

* junctions: blow if duplicates add to addrmap

77a0f76289 Cleanup jtag dtm (#342) 
* debug: Clean up Debug TransportModule synchronizer

With async reset async queues, I feel its safe/cleaner
to remove the one-off "AsyncMailbox verilog black-box
and use the common primitive.

I also added some comments about correct usage of this
block. Probably the 'TRST' signal should be renamed
to make it less confusing, as it requires some processing
of the real JTAG 'TRST' signal.

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))))

d0572d6aab Allow reset vector to be set dynamically 
A chip's power-up sequence, or awake-from-sleep sequence, may wish to
set the reset PC based upon dynamic properties, e.g., the settings of
external pins.  Support this by passing the reset vector to the Coreplex.
ExampleTop simply hard-wires the reset vector, as was the case before.

Additionally, allow MTVEC to *not* be reset.  In most cases, including
riscv-tests, pk, and bbl, overriding MTVEC is one of the first things
that the boot sequence does.  So the reset value is superfluous.
