Guides (Should work in theory for the other Lumia's specified in the EDK2 port as well.)

- [4] Close to mainline linux kernel w/ support for dempsey and a few other msm8x26 lumias on msm8x26 branch. Use msm8x26-touchscreen branch for touchscreen, until it gets committed into msm8x26.
- [5] EDK2 for dempsey, tesla, makepeace and superman. This does boot Linux!
- [6] LittleKernel for tesla and some other lumias. This does not boot Linux!! Useful for chain loading lk2nd to dump regulators when porting a lumia to linux.
- [7] Boot shim used to boot EDK2.
