Unable to compile the project if TLBs are disabled

[donlon]

When I set HasDTLB and HasITLB to false in Settings.scala, the project could not be compiled. The output of make command is

[deprecated] class utils.FlushableQueueIO (1 calls): Unable to automatically infer cloneType on class utils.FlushableQueueIO. cloneType is now implemented by the Chisel compiler plugin so please ensure you are using it in your build. If you cannot use the compiler plugin or you are using it and you still see this message, please file an issue and let us know. For those not using the plugin, here is the 'runtime reflection' cloneType error message: constructor has parameters (entries) that are not both immutable and accessible. Either make all parameters immutable and accessible (vals) so cloneType can be inferred, or define a custom cloneType method.
[warn] There were 1 deprecated function(s) used. These may stop compiling in a future release - you are encouraged to fix these issues.
[warn] Line numbers for deprecations reported by Chisel may be inaccurate; enable scalac compiler deprecation warnings via either of the following methods:
[warn]   In the sbt interactive console, enter:
[warn]     set scalacOptions in ThisBuild ++= Seq("-unchecked", "-deprecation")
[warn]   or, in your build.sbt, add the line:
[warn]     scalacOptions := Seq("-unchecked", "-deprecation")

make: *** [Makefile:24: build/TopMain.v] Error 1

Running make with CORE=embedded (make PRJ=myproject BOARD=pynq CORE=embedded STANDALONE=true) produces the same error. Could you give some help on it?

This patch works for me. Thanks
