Be careful with your terms. It is trivial to access "global data"  in
SA apps as the GD pointer is passed in a register - but "Global Data"
in U-Boot is something which has nothing to do with flash_info[].

You can export and call in SA apps functions which perform operations
on flash_info[], but you cannot  access  flash_info[]  or  any  other
global variables directly.

Note that this is intentional.
