While this is often needed on platforms where ATF encapsulates U-Boot, it is not the case on some other platforms where it's U-Boot that encapsulates parts of ATF. In order to prepare the support for the later platforms, we make building the FIP image optional, and update the only defconfig we have that uses ARM Trusted Firmware. Note: we considered adding a "default y" here to preserve backward compatibility, but there really isn't any default that is sane: whether a FIP image needs to be built or not is purely platform specific.
