Ah, that's what I was looking for.

I know, I know.

I've got that mostly done.  It took me a little while to figure
out that I needed to add my new target to both the targets and
packages files.

Next, I need to modify the linker command file for my target to
add "glue" sections and add some "provides" to set the
addresses of periperals.  I can do this by adding lines to
mlt_arm_mustang_ram.mlt or I can delete the .mlt file and edit
the .ldi file directly -- right?
