Modern Systems-on-Chip (SoCs) are networks of heterogeneous cores, intelligent devices, and memory, connected through multiple configurable address translation and protection units like IOMMUs and System MMUs.

Modern hardware platforms are increasingly complex and heterogeneous. System software uses a hodgepodge of different mechanisms and representations to express the memory topology of the target platform. Considerable maintenance effort is required to keep them in sync while often sharing is impossible due to hard-coded values. Incorrect platform-specific values in the hardware initialization sequence can lead to security critical and hard-to-find bugs because of misconfigured translation hardware, inaccessible devices, or the use of bad pointers.
