I hear you there.
The problem is, of course, that OpenFirmware is a MUCH richer environment than
would otherwise be provided by your U-Boot ROM; rather U-Boot is more akin to
x86 BIOS and thus GRUB2 would likely be more likely able to support booting on
ROMs like U-Boot's, as use of the latter would involve booting via a compressed
ramdisk image of some type; booting from a OF ROM generally involves extensive
use of OF calls to allocate and map memory until the kernel is able to do so
itself.
