Good idea. I've seen the FIT support patches and I think FIT looks reasonable, at least for loading Linux. Would FIT support require discussion/cooperation with other projects like Linux or u-boot? > Can you provide a ling to the Linux calling conventions for riscv ? I think a document like https://www.kernel.org/doc/Documentation/arm/Booting hasn't been written yet for RISC-V. It's something like this: - Linux starts in Supervisor Mode, but in physical address space, and expects a working Supervisor Binary Interface[0] - register a0: hart ID - register a1: pointer to FDT Jonathan [0]: https://github.com/riscv/riscv-sbi-doc/blob/master/riscv-sbi.md
