1df7f0b6a0 x86: kconfig: Let board select SPI flash
Only a specific type of SPI flash exists on a board, having board
Kconfig to select the SPI flash seems to make more sense. Other
flash types are not necessary except coreboot, which implies all
available flash drivers there.

5d89b37f71 x86: kconfig: Select ARCH_EARLY_INIT_R in the platform Kconfig
This is architecture-dependent early initialization hence should
be put in the platform Kconfig.

30b1ecd265 x86: kconfig: Let board select BOARD_EARLY_INIT_F
CONFIG_BOARD_EARLY_INIT_F literally indicates board-specific codes
and should be not 'default y' for all x86 boards.

374e78efb0 x86: Add support for the samus chromebook
This adds basic support for chromebook_samus. This is the 2015 Pixel and
is based on an Intel broadwell platform.

Supported so far are:
- Serial
- SPI flash
- SDRAM init (with MRC cache)
- SATA
- Video (on the internal LCD panel)
- Keyboard

Various less-visible drivers are provided to make the above work (e.g. PCH,
power control and LPC).

The platform requires various binary blobs which are documented in the
README. The major missing feature is USB3 since the existing U-Boot support
does not work correctly with Intel XHCI controllers.
