[coreboot] [PATCH] VIA C7 CAR doesn't configure the stack pointer

[Patrick Georgi]

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)
