63679bb019 Add support for L1 data scratchpads instead of caches 
They fit in the same part of the address space as DRAM would be, and
are coherent (because they are not cacheable).

They are currently limited to single cores without DRAM.  We intend
to lift both restrictions, probably when we add support for
heterogeneous tiles.

dc9ae19936 Work-around for current Scala compiler "structural type loses implicits". 
Running rocket-chip through the chisel3 gsdt branch which supports stricter connection checks and uses implicit definitions to deal with "old" direction overrides, exposed a possible bug in the Scala compiler.

    [error] .../src/main/scala/uncore/devices/Prci.scala:27: value asOutput is not a member of uncore.devices.PRCIInterrupts{val mtip: chisel3.core.Bool; val msip: chisel3.core.Bool}
    [error] possible cause: maybe a semicolon is missing before `value asOutput'?
    [error]   }.asOutput
    [error]     ^
    [error] one error found
    [error] (uncore/compile:compileIncremental) Compilation failed

This change isn't strictly required for current chisel3 code, but is being submitted in anticipation of an eventual merge of the gsdt branch prior to a compiler fix.

c05ba1e864 Add TileId parameter, generalizing GroundTestId 
This usually shouldn't be used in Tiles that are meant to be P&R'd once
and multiply instantiated, as their RTL would no longer be homogeneous.
However, it is useful for conditionalizing RTL generation for
heterogeneous tiles.

07d48df88a Get rid of FPU RoCC port logic when RoCC not present 
The previous approach used ex_reg_valid to determine whether to
source data from the FPU or RoCC.  Thus, when the RoCC was not
present, it was still creating muxes.  Using ex_cp_valid instead
gets rid of them.
