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=<non_standard_text_start> Signed-off-by: Anup Patel <anup.patel@wdc.com> Reviewed-by: Atish Patra <atish.patra@wdc.com>

OpenSBI Supported Platforms
|
|
===========================
|
|
|
|
OpenSBI currently supports the following virtual and hardware platforms:
|
|
|
|
* **Generic**: Flattened device tree (FDT) based platform where platform
|
|
specific functionality is provided based on the FDT passed by previous
|
|
booting stage. More details on this platform can be found in the file
|
|
*[generic.md]*.
|
|
|
|
* **QEMU RISC-V Virt Machine**: Platform support for the QEMU *virt* virtual
|
|
RISC-V machine. This virtual machine is intended for RISC-V software
|
|
development and tests. More details on this platform can be found in the
|
|
file *[qemu_virt.md]*.
|
|
|
|
* **SiFive FU540 SoC**: Platform support for SiFive FU540 SoC used on the
|
|
HiFive Unleashed board, as well as the *sifive_u* QEMU virtual RISC-V
|
|
machine. More details on this platform can be found in the file
|
|
*[sifive_fu540.md]*.
|
|
|
|
* **Kendryte K210 SoC**: Platform support for the Kendryte K210 SoC used on
|
|
boards such as the Kendryte KD233 or the Sipeed MAIX Dock.
|
|
|
|
* **Ariane FPGA SoC**: Platform support for the Ariane FPGA SoC used on
|
|
Genesys 2 board.
|
|
|
|
* **Andes AE350 SoC**: Platform support for the Andes's SoC (AE350).
|
|
|
|
* **T-HEAD C910**: Platform support for the T-HEAD C910 Processor.
|
|
|
|
* **Spike**: Platform support for the Spike emulator.
|
|
|
|
* **OpenPiton FPGA SoC**: Platform support OpenPiton research platform based on
|
|
ariane core.
|
|
|
|
The code for these supported platforms can be used as example to implement
|
|
support for other platforms. The *platform/template* directory also provides
|
|
template files for implementing support for a new platform. The *object.mk*,
|
|
*config.mk* and *platform.c* template files provides enough comments to
|
|
facilitate the implementation.
