".out" is not any known linker output format.  Do you mean a.out?  It
has been ages since I've seen this used the last time - way back in
the previous millenium.

In general, you can use objcopy (from the GNU binutils package) to
convert into raw binary format.  This you can then either load
directly, or wrap it using the mkimage tool into either a legacy
U-Boot image or a FIT image, which then can be started by U-Boot.

Best regards,

: 1.  What is the possibility of this being added in the future?
In the near future, the probability is close to zero. In the  distant
future, I'll be dead, and posterity can do whatever they like... :-)
