platform: ariane: Move ariane platform from fpga to generic

2025-11-05T15:52:41Z

The Ariane framework has a generic PMU that is not used by OpenSBI. Due to OpenSBI’s build system we cannot directly reuse the generic platform functions, so move the Ariane platform to generic. Also due to the generic platform is where new features are added.

platform: Add generic FDT based platform support

2020-05-01T05:03:05Z

We add generic FDT based platform support which provides platform specific functionality based on the FDT passed by previous booting stage. By default, the generic FDT platform makes following assumptions: 1. platform FW_TEXT_START is 0x80000000 2. platform features are default 3. platform stack size is default 4. platform has no quirks or work-arounds The above assumptions (except 1) can be overridden by adding special platform callbacks which will be called based on the FDT root node compatible string. By default, we compile OpenSBI generic platform as follows: $ make PLATFORM=generic For a non-standard FW_TEXT_START, we can compile OpenSBI generic platform as follows: $ make PLATFORM=generic FW_TEXT_START= Signed-off-by: Anup Patel Reviewed-by: Atish Patra

platform: Add OpenPiton platform support

2020-03-24T07:48:38Z

OpenPiton is a research platform from Princeton University [1]. "OpenPiton is the world's first open source, general purpose, multithreaded manycore processor. It is a tiled manycore framework scalable from one to 1/2 billion cores." Add OpenSBI support for OpenPiton. As it is based on ariane core, it reuses the platform code from arine project.
