From: Emanuele Ghidoli <emanuele.ghid...@toradex.com> Add register address and relevant bitmasks and shifts. Allow reading these information: - device identification - number of cores (part of device identification) - features (currently: PRU / no PRU) - security - functional safety - speed grade - temperature grade - package
