As always, when doing a new board, get a system that is known to work with coreboot and has your chipset in it. You should get several (never just one!) of the haswell chromebooks, build coreboot, make sure you can make it all work, then try the port to your board.

Dear coreboot,

We are interested in coreboot for the Intel Haswell processors.
coreboot appears to be used in the Acer C720 and HP Chromebooks
that use Haswell processors.  I see no reference to this processor,
or to these products in the source code that I downloaded recently.

Are you sure? 'git grep haswell' turns up 160 references as of 931c1d.


There is also no reference to these products in the "products
supported" web page of coreboot.org.

 
We are developing hardware using the Haswell processor and 82C226
PCH part.  How do we port coreboot to these devices?  As Acer and HP
have done it, it's obviously possible.

Start by grepping for NORTHBRIDGE_INTEL_HASWELL in the source tree.

Note: The following URL has a codename <--> marketing name decoder for Chromebooks: http://www.chromium.org/chromium-os/developer-information-for-chrome-os-devices 

Any advice gratefully received!

Thanks, Paul.
