Did you check which configurations the Yocto project are using?  They
provide qemu based emulations for ARM, MIPS, PPC and x86, and I would
be really surprised if the ARM and PPC configs were not based on
U-Boot ...  [ARM: beagleboard; PPC: mpc8315e-rdb; MIPS:

If you need BE systems, use PPC.  For ARM, they are just a tiny
minority (so far at least) that I don't think it makes sense to invest
efforts in these.
