On 9263 the sram is huge so you can build barebox as first stage

I add this a long time ago on usb_a9263_bootstrap_defconfig
or other (all the EK).

This will build a barebox that can load you image from multiple source in a sequence

and then use a std barebox

To switch to DT you will have to import the DT I did for the kernel
and replace the hw i2c by a i2c gpio as the i2c IP on at91 has a lot of quirks
and for barebox it will not make sense to port it

Best Regards,
J.
