Not much is happening yet, when the board is enabled (in the next
patch), all three components build successfully, the map files show
them placed where expected and the bopotblock is wrappeed in a BIMG
header.

BUG=chrome-os-partner:31438
TEST=when config is enabled, emerge-urara coreboot succeeds. more
    extensive testing to come later
