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 fundamentalAHB/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=andes/ae350* parameter to the top level make command.
Platform Options
----------------
The Andes AE350 platform does not have any platform-specific options.
Building Andes AE350 Platform
-----------------------------
To use Linux v5.2 should be used to build Andes AE350 OpenSBI binaries by using the compile time option FW_PAYLOAD_FDT_PATH.
AE350's dts is included in https://github.com/andestech/linux/tree/ast-v3_2_0-release-public
**Linux Kernel Payload**
```
make PLATFORM=andes/ae350 FW_PAYLOAD_PATH=<linux_build_directory>/arch/riscv/boot/Image FW_PAYLOAD_FDT_PATH=<ae350.dtb path>
```
