This has been the normal mode of operation for the embedded boards.
Many of us think it is the logical approach, and quite a while ago
some of us started talking about how we can combine these ideas
in an effort to remove a reasonable amount of board specific code
from the kernel setup functions.

There were some challenges while trying to move from one method
to another, with the transition being the 2.4 source tree.  For
2.5 we just "declared" this will be the way.

There are people that want to do this and see value in doing so.  It
does present a challenge as I was one that broke ppcboot when I changed
the interface between the bootloader and the kernel (thinking everyone
used the bootloader wrapper on embedded boards :-).
