[coreboot] Bug?: Value in .config overwritten during make (Thinkpad T400/T500)

Hi folks,

after several hours of trial & error I finally realized why the quadcore CPU in my T500 does not get recognized: No matter what you set for MAX_CPUS in .config, it gets overwritten during the build with a value coming from


where the following is defined:

config MAX_CPUS
        default 2

Well, at least for me default means that it's a default, not that it overwrites the actual config. Is this behavior really intended?

Cheers, Daniel
