The HSS firmware has a very old OpenSBI linked to it as a library. The OpenSBI is a moving target and a lot of features/fixes keep adding to OpenSBI. To tackle this, latest HSS has a compile time option for custom boot flow . The HSS custom boot-flow allows us to: 1. Use OpenSBI generic platform fw_payload.bin (with u-boot.bin embedded) as HSS payload 2. Use U-Boot SPL (in-future) as HSS payload I am able of use latest OpenSBI generic platform and U-Boot S-mode without any issues, to try this: 1) Compile u-boot.bin with this series 2) Compile OpenSBI generic fw_payload.bin using: make PLATFORM=generic FW_PAYLOAD_PATH=<u-boot-directory>/u-boot.bin FW_FDT_PATH=<u-boot-directory>/arch/riscv/dts/microchip-icicle-kit-a000.dtb > + > +Creating the HSS payload > +------------------------ Please have a separate section for steps to compile HSS software for both Microchip boot-flow and Custom boot-flow.
