add_memmap() will also add memory range with type RANGE_ACPI and RANGE_ACPI_NVS (RANGE_RESERVED in the future) besides RANGE_RAM to memmap_p. Among these types of memory range, only RANGE_RAM needs to be aligned with certain alignment. RANGE_ACPI, RANGE_ACPI_NVS and RANGE_RESERVED doesn't have to be aligned.
