I think the following should go here as such lines have recently
been added to other SoC setup files.
.init_late = shmobile_init_late,

Hi Ulrich,
Thanks for your patches. This hunk with loadaddr can go away. It is
specific to ALT anyway. Also, we use dynamic calculation of the load
address in case of zImage and multiplatform, so you want to make sure
to use zImage instead of uImage and then this is not needed.
Cheers,
