Which version of QSys are you using? Which master is the SPI component connected to? Could you share your qsys file?

I've tried on one of my designs and QSys does allocate 32 bytes, as expected. Of course in that case it doesn't allow the address 0x4f0, as it makes the decoding more difficult and suggests 0x4e0 or 0x500 instead.
