Hi all,
I have an AMD Bettong demoboard supported by coreboot and the default configuration works ok.
I've been able to boot a debian8 with a 4.17.1 kernel using the SeaBios payload. Now I've connected
a TPM 1.2 to the LPC bus and I've done the next changes to the coreboot master code

Now the demoboard boots and a new option for TPM is displayed on screen (t for TPM actions),
the grub is loaded ok, but the kernel complains with the next lines I've been able to write down
from a pic I took with the phone.

Anybody could help me to make the board boots again?
