Hi,
the attached patch sets up the stack pointer in the c7 CAR-post routine, to
make function calls work in the small area after CAR and before coreboot_ram.
For sufficient high loglevels, there are two printk_*s in generic CAR code
that made the system reboot. (with my preceding patch, it crashes for all
loglevel configurations and an issue like this one would have been found
directly)
