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?
