I don't add meta-yocto-bsp to my bblayers configuration.

If you want to build your own version of BOOT.bin, its quite simple. Just take the 
u-boot.elf file, and use SDK to create a simple zynq_fsbl project. From that create
the boot image, using the SDK, and add the system.bit, zynq_fsbl.elf and u-boot.elf
binaries. Rename the produce binary to BOOT.bin, and you're good to go.

You can find more information of the boot image creation process on section 3.5,
page 29, of the UG821 - Zynq-7000 EPP Software Developers Guide v3.0.

From within SDK, it's pretty straightforward, and it will automatically create the bif file
after you've specified all the binaries, and create the bootable image.
