Since I'd be chainloading barebox from the existing U-Boot, which does support loadb and bootm, it probably makes the most sense initially to just skip the lowlevel init, and build a minimal ARM second stage, and wrap it in a u-boot image, I think. I tried using the at91sam9263ek_defconfig, and unsetting CONFIG_MACH_DO_LOWLEVEL_INIT.
that won't work : you don't have the same memory mapping so barebox has little chance to be in ram on your platform and, even if it was in RAM as soon as it will poll for the serial port tx empty bit, you will stay blocked because your serial port is not the same as the at91sam9263.
