dfa61bc487 Standardize Data.holdUnless and SeqMem.readAndHold 
- Make API more idiomatic (x holdUnless y, instead of holdUnless(x, y))
- Add new SeqMem API, readAndHold, which corresponds to most common
  use of holdUnless

735e4f8ed6 diplomacy: use HeterogeneousBag instead of Vec 
This makes it possible for the bundles to have different widths.

Previously, we had to widen all the bundles passing through a node
to the widest of all the possibilities.  This would mean that if
you had two source[] fields, they end up the same.

5045696f92 TLRational: test all corners 
In order to ensure that verilator is happy, we launch both clocks from a
clock divider.  Sadly, it does not follow the spec wrt.  derived clocks.

See the verilator manual section on "Generated Clocks".

91d1880dbf ClockDivider2: fix launch alignment of clocks (vcs) 
Doing this in Chisel leads to non-determinism due to shitty
Verilog ordering semantis. Using an '=' ensures that all of
the clock posedges fire before concurrent register updates.

See "Gotcha 29: Sequential logic that requires blocking assignments"
in "Verilog and SystemVerilog Gotchas" by Stuart Sutherland, Don Mills.

e51609aec0 build: support waveform debug using opensource tools 
VCS is not free. Neither is the vcd format.
Fortunately, verilator and gtkwave ARE free ... and faster too.

This patch adds targets:
	run-regression-tests-fst
	run-asm-tests-fst
... which create opensource-compatible fst waveforms for gtkwave.

e8c8d2af71 Heterogeneous Tiles (#550) 
Fundamental new features:

* Added tile package: This package is intended to hold components re-usable across different types of tile. Will be the future location of TL2-RoCC accelerators and new diplomatic versions of intra-tile interfaces.
* Adopted [ModuleName]Params convention: Code base was very inconsistent about what to name case classes that provide parameters to modules. Settled on calling them [ModuleName]Params to distinguish them from config.Parameters and config.Config. So far applied mostly only to case classes defined within rocket and tile.
* Defined RocketTileParams: A nested case class containing case classes for all the components of a tile (L1 caches and core). Allows all such parameters to vary per-tile.
* Defined RocketCoreParams: All the parameters that can be varied per-core.
* Defined L1CacheParams: A trait defining the parameters common to L1 caches, made concrete in different derived case classes.
* Defined RocketTilesKey: A sequence of RocketTileParams, one for every tile to be created.
* Provided HeterogeneousDualCoreConfig: An example of making a heterogeneous chip with two cores, one big and one little.
* Changes to legacy code: ReplacementPolicy moved to package util. L1Metadata moved to package tile. Legacy L2 cache agent removed because it can no longer share the metadata array implementation with the L1. Legacy GroundTests on life support.

Additional changes that got rolled in along the way:

* rocket: 	Fix critical path through BTB for I$ index bits > pgIdxBits
* coreplex: tiles connected via :=*
* groundtest: updated to use TileParams
* tilelink: cache cork requirements are relaxed to allow more cacheless masters

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.

this should be a second-order effect, so using FIFO always is fine.

0baa1c9a45 coreplex: CacheBlockOffsetBits was wrong! 
This bug is ancient. I don't understand how it never mattered before.
Anyway, in processors with a custom CacheBlockBytes, this value is wrong!
The symptom is that TL1 components end up missing high address bits.
This causes, for example, a system to jump to 0 instead of RAM.

I don't understand how this very serious bug did not cause problems before.
