[U-Boot] [PATCH v3 00/10] x86: Add support for samus

[Simon Glass]

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.

Changes in v3:
- Add more detail to the commit message and code comments
- Add new patch top include missing pci.h header in me_common.c
- Add new patch top include missing pci.h header in power_state.c
- Add source coreboot version information to the commit message
- Rename pch_common.c to pch.c

Changes in v2:
- Rename sdram to mrc
- Rename sdram_common.c to mrc.c
