[coreboot] t420 CPU Upgrade

https://www.coreboot.org/Board:lenovo/t420 How stable is the i7-3720qm CPU Upgrade in the t420?  You guys have it listed under the tested portion.  I want to grab myself one, but would want to see if it's worth my time to upgrade the CPU, or just go with something more powerful. -- coreboot

Hi chub, I have a 3740qm in mine, runs fine with the minor constraint that it isn't completely full-load-stable - apparently something decides to shutdown the machine at 100°C core temp before the cpu reduces boost from 3.5 GHz - happens to me in the third run of a kernel build with make -j8.
