Device Tree Generator
A Device Tree is a data structure that describes the underlying hardware to an operating system -
primarily Linux. By passing this data structure to the OS kernel, a single OS binary may be able to support
many variations of hardware. This flexibility is particularly important when the hardware includes an
FPGA.
The Device Tree Generator tool is part of Altera SoC EDS and is used to create device trees for SoC
systems that contain FPGA designs created using Qsys. The generated Device Tree describes the HPS
peripherals, selected FPGA Soft IP and peripherals that are board dependent.
