But as I pointed out apparently other boards need something like that too:
No.

The TRAB board will perfectly reset the board if you remove this code. It just doesn't look as nice (flicker on the display). That's what I meant that some boards may _want_ such a function.
So reset is cpu (better SoC) specific and might even be board specific.
You may want to run board-specific code _before_ reset, but the reset operation itself should IMHO not depend on board specific features. It's always processor (CPU or SoC or what you may call it) specific.
Of coures we can clobber cpu/arm920t/start.S with reset code for every cpu, SoC and board ... adding loads of nice #ifdef's ;-)
This is certainly NOT my intention. I think I explained before what I have in mind.
