HAL Component — MESSAGE
INSTANTIABLE COMPONENTS — General
All instantiable components can be loaded in two manners
Using loadrt with or without count= | names= parameters as per legacy components
Using newinst, which names the instance and allows further parameters and arguments
primarily pincount= which can set the number of pins created for that instance (where applicable)
