Add IPXact schema.

[chick]

Initial porting of old rocket-dsp-utils IPXact wrapper

Add AXI GCD example

Add regmap annotations to AXI4GCD example

Generate some xml based on ipxact annotations. More to do, get ports and port mappings done

• Fixed up header section

• Added model section

  • includes ports and recursively walked fields

• Created IpxactModuleAnnotation

• Create a devices package under ipxact

  • Place to put portMapping and other specific code
  • Added AXI4Device
  • Added AXI4StreamDevice

• Added a name parameter to RegFiedlDescMapping generation method

• Fixed doubled generation

• Added new busIntervace generation code

• moved work dir for axi4gcd to test_run_dir/axi4gcd

• cleaned up main in IpxactGeneratorTransform

• cleaned up main in PrintMe

Retooling how annotations are processed into XML changing things so that, for example, is not included unless there one or more inside. Looking at making two transforms, one to memoize the bundles at HighForm so they can be used to organize the expanded bundle fields later

Created two transforms, the first one operates on HighForm and memoizes annotated bundles for use in the second pass BusInterface mappings are now generated

Move AXI4GCD from test to main

Add regmap annotations to AXI4GCD example

• Created IpxactModuleAnnotation
• Create a devices package under ipxact
  • Place to put portMapping and other specific code
  • Added AXI4Device
  • Added AXI4StreamDevice
• Added a name parameter to RegFiedlDescMapping generation method
• Fixed doubled generation
• Added new busIntervace generation code
• moved work dir for axi4gcd to test_run_dir/axi4gcd
• cleaned up main in IpxactGeneratorTransform
• cleaned up main in PrintMe

Added support for multiple ipxact modules to be created during pass

• Foreach IpxactModuleAnnotation
  • Find other IPXACT annotations that refer to same circuit
  • build xml using those
  • write a distinct xml file for this module.

Fix component xml namespace declarations

re-adding Ipxact.scala

I've made some progress on using aspects here. The issue I'm currently running into is: 1) Getting the scheduling of the IPXact passes to work with the aspect passes 2) Some rocket stuff is being called that annotates stuff. It doesn't return annotations, it adds them to the current builder context. Aspects don't pick stuff up from the builder context (in fact, I don't think a builder context exists at all)

Stale. Please re-open if you are interested in continuing this PR.
