The addresses may be different than normal u-boot (though we could take
care of that by preprocessing the linker scripts), and you don't need to
pull in as many sections (though it would be harmless to do so if those
sections are empty in the loader).  mpc8313erdb uses the nand_spl linker
script to provide a link-time warning if the size limit is exceeded.

A more basic question is why does each board need its own linker script,
NAND or not?
