Andrew Waterman
96fa1eb6ad Add UInt->BitPat implicit conversion 
This will be removed from Chisel3, so we're putting it here to maintain
compatibility.

3cc236e9c4 By default, use same TileLink width everywhere 
When there's no L2 with a wide interface, having wider TileLink
is only disadvantageous.

391a9b9110 Use buses, rather than crossbars, by default in TLInterconnect 
We should eventually parameterize this, of course.

8139f71dfb Work around Chisel2 bug 
This code is correct, but Chisel2 erroneously flags it as a Chisel3
compatibility error because it looks like Vec(Reg) when factor=1.

b734beec06 Update build instructions 
The emulator now requires an ELF file even when running ground tests.
(The ELF contains the tohost and fromhost addresses for communication
with the FESVR.)
