Hi,

You should probably try an older version of coreboot, close to when the
harcuvar board was introduced and check if that version outputs anything
on UART.
I did that on a custom board using denverton recently and already
proposed a few fix, but I don't have an harcuvar board to test.

Hope this helps,

Julien
