[0/4] Further zImage work

[David Gibson]

The following patch series is an attempt to consolidate some of the
more settled ideas in the many zImage patches flying around at the
moment.

This patch series needs to be applied on top of patches 4-7 from
Milton Miller's recent series, and patch number 2 from Scott Wood's
most recent cuboot series (patch 1 from that series having already
been applied to powerpc.git).
