[PATCH v2 10/16] x86: coral: Allow booting from coreboot

[Simon Glass]

Set up coral so that it can boot from coreboot, even though it is a
bare-metal build. This helps with testing since the same image can be used
in both cases.

Changes in v2:
- Add missing newline in the error path
- Use (ret) instead of (ret != 0) to fit with U-Boot style
