Understood. Why not? Such a szeario has been discussed  before,  too.
Of  course  a  split set of kernel and DT images has to be supported,
too. The proposed solution was  to  extend  the  "bootm"  command  to
accept a 3rd parameter, the DT address:

	bootm <kernel_addr> <ramdisk_addr> <dt_addr>

<dt_addr> is optional, and '-' can be used when no ramdisk  is  used.
Something like that ...

Of course.

Fine. Thanks.
