Here's the barebox code that implements booting other barebox images: https://git.pengutronix.de/cgit/barebox/tree/arch/arm/mach-layerscape/pblimage.c Apparently entry point is at offset 128K. Keep in mind that U-Boot go (at least on ARM32) does not do cache maintenance or turn off the MMU, so funny effects may be expected.
