It can be truth but this is Microblaze.

nice is that there is written most files.

The reason is that I am configuring several platforms with different DTS 
files and I am retesting that generated files. That's why I need to have 
simpleImage.xxx and simpleImage.xxx.ub in boot folder which have 
different names. I am doing several clean-ups but I need to store that 
files.

mrproper        - Remove all generated files + config + various backup files

If you look at help for mrproper we can call that files like backup files.


I agree with you that will be good to remove them but only for make 
mrproper as was written in your commit message.
