Can you do make clean and #define DEBUG and rebuilt and reflash debug build of u-boot. This should enable those debug output.
Here's what I get:

I'm currently studying what all this means, but I figured I email it now anyway.
I will look at some AMD part datasheets. If this is generally available on all AMD and AMD like parts, we can add it as a patch for AMD only. Otherwise, we will either add CONFIG_GEOMETRY_REVERSED definition or restrict a patch to specific vendor ids (and possibly part ids) which is then a pain to manage.
I'd like to help with this endeavor, although I currently don't know a whole lot about flash programming.
