Subject: Start of Minikin integration

This is the current state of the Minikin integration. All changes are
hidden behind USE_MINIKIN #ifdef, so it should be safe to apply. To
play with the Minikin branch, set this in your BoardConfig.mk .

This change also merges in 64-bit changes that were happenening in
parallel.
