Hi Bill,
In board/MAI/AmigaOneG3SE/Makefile some of the files listed in $(COBJS) 
don't exist, eg ../bios_emulator/x86interface.c.  $(SRCS) is created 
from $(COBJS), which in turn makes the .depend target in rules.mk fail.

It looks like some of the missing files were removed in this commit:

commit 221838cc7eb178370ff62aa05920a582e12ac322
Author: Jason Jin <Jason.jin at freescale.com>
Date:   Tue Jul 10 09:03:22 2007 +0800

    Remove the bios emulator from MAI board.

    The bios emulator in the MAI board can not pass compile
    and have a lot of crap in it. remove it and will have a
    clean and small bios emulator in the drivers directory
    which can be uesed for every board.

However, as Jason noted the AmigaOneG3SE wasn't compiling prior to his 
commit.

If I were in your shoes I would dig into the current U-Boot code and 
start getting familiar with it as it will likely take a bit of work to 
get the AmigaOneG3SE working again.  Perhaps if you go far enough back 
in U-Boot's history you can find a point where the AmigaOneG3SE will 
compile and run to use as a working reference.  If you know which 
version currently works for you that would be a good starting point.

Best,
Peter
