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.

779653b0cb x86: Drop all the old pin configuration code
We don't need this anymore - we can use device tree and the new pinconfig
driver instead.

9ed781a6ff x86: ivybridge: Move northbridge and PCH init into drivers
Instead of calling the northbridge and PCH init from bd82x6x_init_extra()
when the PCI bus is probed, call it from the respective drivers. Also drop
the Northbridge init as it has no effect. The registers it touches appear to
be read-only.

a5dec5a5c4 x86: cros_ec: Drop unnecessary init
Since driver model will probe the EC when it is first used, we do not
need to init it explicitly.

b71eec3129 x86: ich6-gpio: Add Intel Tunnel Creek GPIO support
Intel Tunnel Creek GPIO register block is compatible with current
ich6-gpio driver, except the offset and content of GPIO block base
address register in the LPC PCI configuration space are different.

Use u16 instead of u32 to store the 16-bit I/O address of the GPIO
registers so that it could support both Ivybridge and Tunnel Creek.

2795573a8c x86: ich6-gpio: Move setup_pch_gpios() to board support codes
Movie setup_pch_gpios() in the ich6-gpio driver to the board support
codes, so that the driver does not need to know any platform specific
stuff (ie: include the platform specifc chipset header file).

8ef07571a0 x86: Add chromebook_link board
This board is a 'bare' version of the existing 'link 'board. It does not
require coreboot to run, but is intended to start directly from the reset
vector.

This initial commit has place holders for a wide range of features. These
will be added in follow-on patches and series. So far it cannot be booted
as there is no ROM image produced, but it does build without errors.
