please remove this patch (better both of them because they were in
series) because they are breaking at least ZynqMP SPL. It is also too
late in cycle to create random fix.
You can't simply move 64KB from code to malloc without reflecting this
by changing MALLOC space size.
Other boards with SPL fat could be also affected by this if they don't
allocate big malloc space.
