Hi Hamo,
Welcome to coreboot. While you are working on your project idea you should also be making yourself familiar with coreboot. Please go through the process of downloading, building, and running coreboot on a mainboard, or SimNow, or QEMU.
Thanks. I have already checked out the source code of Coreboot and built a few with the payload Seabios and Linux kernel. Since I don't have a mainboard supported by Coreboot, I have to run it on QEMU. I am analyzing the source code and trying to get familiar with it.
When considering your project, think about the hardware and tools you will need for development. Bari, Ron, and Jason may have some recommendations on what target to use.
