90 k is a funny size. It does not match typical flash  sector  sizes.
How did you come to such a size restriction?

No. if you think about the code needed to do that you will  soon  see
that  this  does  not  fit  into  U-Boot's  design principles (easily
portable, provide success [and error!] messages as early as possible,
etc.).

Use latest compilers, i. e. GCC 4.x; they optimize much  better  than
older versions.
