[coreboot] Please help me adapt coreboot to HiFive-Unleashed

[王翔]

I tried to adapt coreboot to HiFive-Unleashed and boot bbl with coreboot and run linux.
My changes are as follows:
    https://github.com/hardenedlinux/coreboot-HiFiveUnleashed/tree/HiFive-Unleas...

My code can run bbl, but it doesn't respond when bbl exits m-mode and enters linux.

I use freedom-u-sdk to compile bbl. In order not to conflict with the coreboot memory address, execute the following command.
riscv64-elf-objcopy --change-addresses 0x200000 work/riscv-pk/bbl ../coreboot/payload.elf

I don't know what I missed, what should I do, I hope to get your help.
