Chromebook support

[rmsyn]

Hi, I recently started looking at supporting Chromebook builds in oreboot.

Maybe following a similar pattern to #533, except with the need to include an Intel binary blob (looking at an x86_64 mainboard).

I have a Chromebook CB311-9H (octopus-bobba) piece of hardware to test on, and have started porting the C code from coreboot in my cb311 branch.

So far, just have the EC ACPI ASL files copied over, and some of the EC code ported. Will need to add some parser code in a build.rs using the acpi crate.

Before I go too much further, is this something that oreboot wants to pursue? I'm happy to take this on as a project, and shouldn't need too much oversight.

Mainly just don't know how more experienced project members feel about the binary blob...

wow. Cool. But a question. Have you considered an ARM chromebook, which would be much more open source? but if you still want to do this, you are most welcome here!

Have you considered an ARM chromebook

Definitely, I had one at one point, and wouldn't mind getting one again for this project. The stuff I'm working on now is for the EC (common to all Chromebooks, I think).

I'll probably be doing this in stages (EC support, mainboard, bobba variant, etc). When I get closer to having something ready for review, I'll ask about how you want me to split it up. Who knows, I may have an ARM Chromebook by then :)
