Hi Simon,

This series adds support for samus, the Chromebook Pixel 2015. Since it is only the second board added that does not use an FSP, there is quite a bit of refactoring involved to avoid code duplication.
Samus uses roughly the same binary blobs as link, except now there is one more called the reference code binary. The only available binary for this is a coreboot 'rmodule' extracted from flash. This is a simplified ELF format so it fairly easy to load and use.
It is also possible to boot U-Boot from coreboot on samus. This works well but for a delay for non-existent IDE on start-up. The standard build does not work with binaries taken from flash, so it isn't easy to replicate this - you'll just have to take my word for it. I am working on getting that figured out - coreboot recently gained upstream support for loading U-Boot as a payload, so it should be possible to get this working nicely before long.
In any case much of the code comes from coreboot - individual files are credited with their source.
Perhaps the main value of this series is the improved non-FSP support and additions for broadwell, which samus uses. It should make it easier to add support for future non-FSP platforms.
I've applied 18 patches to u-boot-x86/next which don't have inter-dependencies and buildman builds fine. Please rebase your future patches on top of that. Thanks!
Regards, Bin
