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.
