- GAUDI ASIC support. The tag contains code and header files needed to
  initialize the GAUDI ASIC and run workloads on it. There are changes to
  the common code that are needed for GAUDI and there is the addition of
  new ASIC-dependent code of GAUDI.

- Add new feature of signal/wait command submissions. This is relevant to
  GAUDI only and allows the user to sync between streams (queues) inside
  the device.

- Allow user to retrieve the device time alongside the host time, to allow
  a user application to synchronize device time together with host
  time during profiling.

- Change ASIC's CPU initialization by loading its boot loader code from the
  Host memory (instead of it being programmed on the on-board FLASH).

- Expose more attributes through HWMON.

- Move the ASIC event handling code to be "common code". This will be
  shared between GAUDI and future ASICs. Goya will still use its own code.

- Fix bug in command submission parsing in Goya.

- Small fixes to security configuration (open up some registers for user
  access).

- Improvements to ASIC reset code.
