Hi Xiang,

I think the best way to integrate opensbi for now would be to put it into the payloads/external directory and execute it as a rampayload. (in m-mode)

Hello Dear:

I added some code to support linux binary directly as a payload to boot for RISC-V.

modify:
    1. opensbi is an open source sbi implementation(https://github.com/riscv/opensbi)
    2. Linux binary is used as the payload of opensbi
    3. The elf generated by opensbi compilation is used as the coreboot payload.

Code reference:
    https://github.com/hardenedlinux/coreboot-HiFiveUnleashed/tree/r1

Whether to consider adding opensbi to 3rdparty?
Do you have any suggestions?
