Yes,  assuming  you  have  sufficient  hardware  documentation  (like
schematics) as well.

623? I guess you mean 823? Yes, this is easy to find out. But it will
not help you much. You will still  have  to  port  U-Boot  to  *your*
board.  Forget  about  the  idea  that  two  boards might be "similar
enough" to clone one from the other. They aren't.

You need to understand both the hardware  and  U-Boot,  or  you  will
fail.


And BTW: I think your approach suffers from a serious mistake: to  me
it  makes  little  sense  to  use a MPC8xx based board as model for a
PXA270 target system; there are *huge* differences between these  two
architectures.

Best regards,
