[coreboot] Error with tiano payload

[Jorge Fernandez Monteagudo]

Hi,


I get the next traces when I try to boot a coreboot rom with tiano payload. I've configured

framebuffer graphics resolution (800x600 16.8M-color (8:8:8))

When configured with 800x600 32k-color (1:5:5:5) or 800x600 64k-color (5:6:5) I get

and boots ok. The graphic console is corrupted until the Xorg is running but the board boots...

Any hint is welcome!

Regards
Jorge
