2020-03-24platform: Add OpenPiton platform supportAtish Patra2-0/+37
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 Patel1-10/+2
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.

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.

Since, OpenSBI will directly load the pre-built DTB from kernel now onwards, no need to keep the out-of-date DT in openSBI.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.
