[U-Boot] [PATCH] image: Don't relocate ramdisk to highmem

Dear Thierry Reding,

Can you please be a bit more explicit?  Which exact architecture are
you talking about?  Can you show a specific example of an error case
for such a system?

I don't like to have such a patch (which affects ALL systems) added
unless we understand exactly why we should do that. 

Why do you not simply set initrd_high as needed?

Also, when changing the behaviour, you should also update the
comments.

Best regards,

Wolfgang Denk
