8ad8e8a691 Add partial Sv48/Sv57 support 
Right now, we don't support Sv39 and Sv48 at the same time, which needs
to change.

ad93e0226d Changes to prepare for switch to TileLink interconnect 
We are planning on switching to a TileLink interconnect throughout and
convert to AXI only on the very edge. Therefore, we need to get rid of
all the existing AXI masters other than the TileLink to AXI converter.

* Get rid of DMA engine for now
* Connect RTC to TileLink interconnect instead of AXI interconnect

separate btb response mask from the frontend mask
 2016-03-26 18:15:14 -07:00
Christopher Celio
f526d380fd separate btb response mask from the frontend mask 
It is now the job of the pipeline to monitor the frontend's valid mask (of
instructions) and the BTB's suggested valid mask (based on the prediction it
makes). Some processors may want to ignore or override the BTB's prediction and
thus can supply their own instruction mask.

Preliminary Chisel 3 Support

39cf945efb Use Chisel 3 to build verilog on Travis 
Chisel 3 can't build the C++ emulator, so we currently can't have direct
support for testing RocketChip.  We can at least test to see if the
Verilog builds when run through Chisel 3, which this patch does.

cddfdf0929 Add CHISEL_VERSION make argument 
This allows users to specify if they want to build RocketChip against
Chisel 2 or 3.  Since Chisel 3 is now open source we can add these
submodule pointers directly to avoid a fork of upstream.

471f4c2695 change WriteMaskedPutBlockRegression for better bug detection 
Instead of sending puts back-to-back, separate the two puts with a get.
Also, stall a bit between each transaction. This makes sure the puts and
intermediate get are sent to the same transactor, which will cause the
data buffer to get overwritten between the two puts.
