[U-Boot] [PATCH v4 0/5] Add a coreboot board, CPU, and configuration, and target.

[Gabe Black]

This series of changes adds a coreboot board, CPU, configuration, and build
target. These patches are all needed in order to get to a buildable state
and could potentially be merged together into larger changes. Merging them
all would create a change that, in my opion, is a bit too big, so I'll
leave it to the reviewers to decide which patches should be merged.

Changes in v2:
Change capitalization of the x86 tag.
Get rid of some dead/unnecessary code in the Makefile and coreboot.c.

Changes in v3:
Move the Signed-off-by line up.
Change the summary line tag style.

Changes in v4:
Change the summary tag style.

Gabe Black (5):
  x86: Add a target for running as a coreboot payload
  x86: Add a basic implementation for a coreboot board
  x86: Add a preliminary coreboot configuration header
  x86: Add an implementation for a coreboot CPU
  x86: Make the serial port work for the coreboot board
