No, that is not right place. initrd could be loaded anywhere like way high by bootloader. to make code simple, we should have following sequence in setup_arch early_ioremap_init() early_update_microcode()... early_cpu_init() early_update_microcode could use early_ioremap to access initrd ramdisk area.
