You know what?  I agree with you... on a conceptual level only though.

In reality, some people are are just too used to it, either for 
emotional reasons or simply because that's what was there before so they 
simply perpetuated it without thinking further, or whatever.  REmoving 
that support would just upset a lot of people.  And frankly we have 
better things to do than starting a flamewar over this.

So the next best thing is to make this u-Boot stuff well contained in a 
common place and make sure it doesn't spread incoherently over multiple 
architecture's directories and makefiles.  This way the u-Boot cruft 
won't be the ARM maintainer, or the PPC maintainer, or the SPARC 
maintainer, or any other architecture maintainer's business, but the 
responsibility of those who do care about it without affecting anyone 
else.

Why not if someone cares?  At least this will be done only 
once, centrally, without having to involve architecture maintainers.
