AFAIK most embedded board definitions only have enough support to boot
Linux, but not their own firmware or other OSes. Many onchip devices
required to use the firmware are missing, and the only direct kernel
loading mechanism available is the Linux one.
For my Haiku Sam460ex port I started writing a sam460ex target but it's
not published yet nor finished.
It can start our own bootloader faking a Linux kernel, and has enough
faked onchip devices to start the U-Boot image but doesn't get far yet
inside it.
