[U-Boot] Create a Bootable DAS U-Boot pen drive

Hello all,

I'm wondering if in theory it's possible to create a bootable pen-drive with U-Boot on it to allow the following:

1st) Take a PPC Mac Mini for instance that runs OpenFirmware. 2nd) Boot it from the USB Pen-drive 3rd) U-Boot will be loaded 4th) U-Boot would offer the possibility to boot directly from a OS that it's expecting U-Boot as native boot device, like: Amiga OS 4 on Sam440p 5th) Boot occurs normally as it should be if Mac was equipped with U-Boot.

That would be somehow similar with Efi-X that allows installation of OS X directly on regular pc's, right?

Is that possible?

Att,
