yes, it does make the linker scripts a bit more opaque, but since each arch is 
doing something unique, it's fairly hard to merge them into a single file.  the 
Linux approach represents what we can do in the real world -- get beyond 
board-specific linker scripts and to one linker script per arch.  then the 
vmlinux.lds.h merges a lot of the stuff that can be shared between arches.

i've unified all the board/SoC linker scripts for Blackfin and now there is just 
one -- arch/blackfin/cpu/u-boot.lds.
