At present this casts addresses to pointers so cannot work with sandbox. Update the code to use map_sysmem() instead.
As part of this change, the existing load_ptr is renamed to src_ptr since it is not a pointer to load_addr. It is confusing to use a similar name for something that is not actually related. For the alignment code, ALIGN() is used instead of open-coded alignment. Add a comment to the line that casts away a const.
Use a (new) load_ptr variable to access memory at address load_addr.
