d09f43c32f axi4 Bundles: add a size calculation helper 
The old version was wrong.
Inverting before the << has a different width.
This means you end up with high bits set.

a82cfb8306 tilelink2: replace addr_hi with address (#397) 
When faced with ambiguous routing of wmask=0, we decided to include
all the address bits. Hopefully in most cases the low bits will be
optimized away anyway.

this an lead to 'data' changing while 'valid' is high. A violation. The

Queue.

 * 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.

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.

5e34b313ee RegMapper: regmap(...) now takes BYTE addresses 
If a device has configurable bus-width, we need a stable way of
enumerating registers. The byte offset stays unchanged.

This change also makes it possible to put an arbitrary number of RegFields
starting at some address which are then chopped up into appropriately bus-
sized registers.

972ca06729 RegField: remove RegField.bytes; it was dangerous

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))))

12d0c00822 Fix mtime RegField handling 
RegField.bytes was unconditionally overwriting mtime, preventing it
from ever ticking.  Avoid RegField.bytes by splitting mtime into
a Seq of words.
