riscv: how to running coreboot on HiFive Unleashed?

[王翔]

I try to running coreboot on HiFive Unleashed, but nothing come from uart.

I tested by the following steps:

1.  Write hifive-unleashed-a00-1.0-2018-03-20.gpt to TF card.
2. Change MSEL to 11 and boot linux
3. Copy coreboot.rom via scp
4. Write coreboot.rom to /dev/mtd0 by flashcp.
5. Change MSEL to 15 and boot coreboot. No response on uart.

Do you have any suggestions?
