We are working on fixing that with the "u-boot-fdt" subtree, but it is 
slow going and it will not magically fix already fielded boards. 
(Forget that Harry Potter crap magic, _that_ would be some useful magic!)

I think the "proper" solution is not to add the /chosen node in the dts 
but rather to generate a _correct_ one in u-boot.  Note that 
linux,stdout-path is something that _should_ be generated based on the 
u-boot configuration (currently it is hard #defined, IMHO it should be 
part of the u-boot environment).

Looks like it is at fdt_support.c line 152:
