b240505a15 rocketchip: move memory channel Xbar from coreplex to rocketchip 
We want to keep the banks split in the outer SoC if there is an L3.
Furthermore, each channel might go to different memory subsystems,
like DDR/HMC/Zero, from rocketchip.

75edf42323 Set xPIE=1 on xRET 
We were setting xPIE=0 instead.  This is a benign bug, but still a bug.

dc66c8857f diplomacy: be more robust using Java introspection 
If an error occures, some objects might only be partially initialized.
We want to still be able to get nice names for error messages.

280af9684b BankedL2Config: use the same LazyModule for all L2 banks 
This makes it much easier for banked coherence managers to support
cross-bank functionality, like a common control port, for example.

3c1dac8c68 Match chisel3 userootunmanageddir - use RootProject/lib as unmanagedBase. (#526) 
This anticipates ucb-bar/chisel3#448. When rocket-chip uses that version of chisel3, the extra copy to chisel3/lib may be removed.
