at the following:
- __bank_start Symbol marking the start of memory bank window
- (bank_physical)
- __bank_virtual Logical address of symbols for which the transformation
- must be computed
- __bank_page_size Size in bytes of page size (this is *NOT* the memory
- bank window size and the window size is always
