No, you must align to (1 << log2_round_down(size)) - that will always be the largest mbus window created and thus the highest starting alignment requirement. I looked for a bit to see if I could find why the core is rounding up to 196MB and it wasn't clear to me either. Gerlando, if you instrument the code in setup-bus.c, particularly pbus_size_mem, you will probably find out.
