The reason is that in write_tables() rom_addr is not aligned and copied to gd->arch.smbios_start. The Simple Firmware Interface requires that the SFI table is paragraph- aligned but our code does not guarantee this. As all tables written in write_tables() must be paragraph-aligned, we should implement the address rounding in write_tables() and not in table specific routines like copy_pirq_routing_table(). Add paragraph-alignment in write_tables().
