 From my investigation, Coreboot is issuing this reboot command, because 
the Coreboot payload (which in my case is U-Boot) for some reason isn't 
valid. With CONFIG_PANIC_HANG defined there is no UART output from the 
EC at all.
Is a prepended SPL needed before the U-Boot+DTB payload?

When flashing U-Boot from the Chromium OS branch it gives some UART 
output but freezes because SPI and MMC driver are not working properly 
("emerge-nyan chromeos-u-boot").
Is this the best starting point to develop a working U-Boot?

Regards,
Simon
