At least for the TG3PCI_MEM_WIN_DATA register, I don't know how safe it is to use tw32_f() there. Reads from a location can have side effects, so doing a forced readback after a write could be dangerous.
And it isn't needed, as the tw32_f() done as we set the TG3PCI_MEM_WIN_BASE_ADDR back to zero will flush all posted writes.
