2020-03-24platform: Add OpenPiton platform supportAtish Patra
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.

2020-03-19platform: sifive/fu540: Remove FU540_ENABLED_HART_MASK optionAnup Patel
The FU540_ENABLED_HART_MASK compile time option was added for initial bring-up on SiFive Unleashed. This option is redundant now because disabled_hart_mask is already removed. Based on this rationale, we remove FU540_ENABLED_HART_MASK compile time option.

2020-02-11doc: sifive: fu540: Update QEMU instruction when using U-Boot as the payloadBin Meng
Document that when U-Boot v2020.01 (or higher) is used as the payload, we need adjust the instructions a little bit when testing OpenSBI with QEMU 'sifive_u' machine. Signed-off-by: Bin Meng <[email protected]> Reviewed-by: Atish Patra <[email protected]>
2020-02-07platform: Drop qemu/sifive_u supportBin Meng
With QEMU v4.2 RISC-V changes to improve the emulation fidelity of 'sifive_u' machine, OpenSBI v0.4 / U-Boot v2019.10 / Linux kernel v5.3 images built for the SiFive HiFive Unleashed board can be used out of the box without any special hack. Hence there is no need for us to continue supporting such a special target in OpenSBI. Going forward, sifive/fu540 platform can be used on both real hardware and QEMU 'sifive_u' machine.

2020-01-10docs: platform: Update SiFive FU540 doc as-per U-Boot v2020.01Anup Patel
With U-Boot v2020.01, the SiFive FU540 DTB required by U-Boot is embedded in U-Boot binary itself so we don't need to do anything special for U-Boot v2020.01 as payload to OpenSBI firmware. This patch updates SiFive FU540 documenation assuming we use latest U-Boot v2020.01 release. Signed-off-by: Anup Patel <[email protected]> Reviewed-by: Bin Meng <[email protected]>

With QEMU v4.2 release that has improved the emulation fidelity of 'sifive_u' machine, OpenSBI v0.4 / U-Boot v2019.10-rc1 / Linux kernel v5.3-rc2 images built for the SiFive HiFive Unleashed board can be used out of the box without any special hack. Update our documents to mention 'qemu/sifive_u' platform should only be used with QEMU v4.1 or before, and it will be dropped sometime in the future release. Going forward, 'sifive/fu540' platform can be used on both real hardware and QEMU v4.2+ 'sifive_u' machine. Signed-off-by: Bin Meng <[email protected]> Reviewed-by: Anup Patel <[email protected]>

2019-07-02platform: Remove the HiFive Unleashed expansion board DT.Atish Patra
The Linux kernel will maintain the device tree (DT) for HiFive Unleashed from release v5.2-rc6. This DT is incompatible with previous DT present for Microsemi expansion board in OpenSBI. Since, OpenSBI will directly load the pre-built DTB from kernel now onwards, no need to keep the out-of-date DT in openSBI. Remove this DT and it's related documentation.
