4caa543ad7 tilelink2: Fragmenter should not cut Acquire parameters 
The correct response to misuse is to fail a requirement check.
Pretending that things are not caches could lead to inconsistency.

 * The BlackBox asynchronous reset registers from uncore.tilelink2

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.

* tilelink2: use addr_lo instead of relying on truncation

Truncation can mess up if the width should be 0, but IS 1.

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.

* crossing: use async reset

* crossings: asyncqueue needs Asynchronous reset.

* crossing: Actually enable the head of the synchronizer flop chain

* crossing: remove reset from logic. This flop will no longer be written during reset because valid will be low.

* crossing: Tidy up code  & comments

This moves the Xbar from using custom code to using the Arbiter.
The arbiter has better ready-valid decoupling.

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 
The implementation unconditionally drove the register.
This made it incompatible with drivers from the device itself.
Besides, writing only parts of a register at a time is ultra-shady.

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))))
