It should be possible for those systems that want a generic linux
distro to run on them. AFAIK the wandboard systems are one of those
that do. It's also a system that doesn't ship with any onboard storage
so distros are forced to build u-boot for it.

its not at all, if there is some way to achieve much the same thing
using some other method please let me know. I don't want to force some
solution everywhere. but i want the same solution to be in place for
boards that want to have a generic linux distro be supported on it.

I didn't take out the features we do not want because I understand that
not everyone wants things to be the same, that other ways to do things
is perfectly valid.

and those systems are free to continue as they do today. they are
likely systems where a generic linux distro just wont run even if you
really try.
