For the dtb, I think you could simply provide a patch that adds the dts
file to the pc-bios directory and another one that adds the dtb. Just
like it is already done with pc-bios/bamboo.dts / pc-bios/bamboo.dtb.

For u-boot, can you use the same upstream level as e500 ? I.e. check
whether "git submodule status roms/u-boot" is fine for you? If that's
ok, just do a "git submodule update roms/u-boot" and build uboot from
that directory - you then can submit a binary patch with that file for
pc-bios, too.

In case you need another u-boot version, I think you've got to update
the submodule to the newer upstream version first, and then also rebuild
the e500 binary... Cumbersome, but that's necessary since we've got to
ship the u-boot sources in the QEMU release tarballs, too, to be
compliant with the GPL.
