[coreboot] Supporting a new board

[Alif Ilhan]

I previously wanted to port coreboot to my machine. But due to the lack of
FSPs, specially the MRC.bin for Cedar trail platforms, I couldn't do it.
But, I have recently found the source code for an Intel Cedar trail bios.
It is actually an AMI bios source code. It has a huge amount of very
useful information like Memory Init, Power management etc. And has almost
everything open source except the EC. I want to ask how can I use it to add
support for coreboot to Cedar trail? Is it possible to use at least the
memory init and the FSP alternatives from the source code? I can share the
code archive if you need to have a look at them
