Good. Note that U-Boot 1.3.0 is very, very old, too.

"new u-boot 1.3.0" is an oxymoron. U-Boot 1.3.0 is nearly two years
old.
I hope you will now learn the lesson of what it gives to you to
maintain an out-of-tree port. If you had pushed your changes upstream
when 1.1.5 was current, you wouldn't have any problems now. I can only
hope that you will do this after adapting your code to a recent code
base (make sure to use top-of-tree from git for this).

It makes no sense to attempt to backport that stuff to such an ancient
release. Please update your code.

We don't access registers through (volatile) pointers any more for
this very reason - today we are using proper accessor functions that
make sure compiler optimizations will do no harm.
Just use current code.
