Certain AP148 platforms (and derivative) use bootloaders which did not have DT enabled. In order to support these old platforms, we'll now make the following modifications: *explicitely add the memory node in the AP148 DT: this used to be added by new u-boot through a run-time patch mechanism. We'll now add it explicitely so it works on boots which don't support that feature. New boots will have the node twice, the second one will be ignored. *add the zImage generation next to the FIT image for AP148. Other platforms using non-DT enabled bootloaders may want to leverage this zImage code to generate their own firmare as well.
