Andes AE350 SoC Platform ======================== The AE350 AXI/AHB-based platform N25(F)/NX25(F)/D25F/A25/AX25 CPU with level-one memories, interrupt controller, debug module, AXI and AHB Bus Matrix Controller, AXI-to-AHB Bridge and a collection of fundamental AHB/APB bus IP components pre-integrated together as a system design. The high-quality and configurable AHB/APB IPs suites a majority embedded systems, and the verified platform serves as a starting point to jump start SoC designs. To build platform specific library and firmwares, provide the *PLATFORM=generic* parameter to the top level `make` command. Platform Options ---------------- The Andes AE350 platform does not have any platform-specific options.
