Changes since 0.5.0

Changed

• AXI interfaces now include the aw_atop signal. Interfaces, macros, and existing modules and
  TBs in this repository have been updated. The ReadMe has been updated to guide users of this
  repository on how to deal with the aw_atop signal.

Added

• Add AXI atomic operations (ATOPs) filter.

Fixed

• Replace non-ASCII characters in Solderpad license text.
• Add a trailing semicolon to the AXI_ASSIGN() and AXI_LITE_ASSIGN() macros in assign.svh
  (#8). Those macros can now be used without a semicolon. Existing code that uses the macros with a
  semicolon do not break.
