Subject: Re: [PATCH] microblaze: Removed U-Boot image creation from
 simpleImage rule

Sorry, I didn't notice that simpleImage.% was the only target to get 
uImage as well.


In this patch there is no simpleImage.%.ub rule, as I got messed up with 
wildcard issues, and I didn't see any point in working on resolving 
them. In practice, I suppose one wants either an U-Boot image or a 
simpleImage. In case both are wanted, it's as simple as mention both in 
the make target.


Patch follows (I made a few other changes as well).
