Since update_flash() is used only in update_tftp(), it should be guarded with appropriate config options.
After the commit 3149e524fc1e, common/update.c will be built under either CONFIG_UDATE_TFTP, CONFIG_DFU_TFTP or CONFIG_UPDATE_FIT. Since CONFIG_UPDATE_FIT, hence fit_update(), doesn't rely on update_flash(), the compiler may cause an "unused" warning if CONFIG_UPDATE_FIT=y and CONFIG_UPDATE_TFTP=n and CONFIG_DFU_TFTP=n.
This is, for example, the case for sandbox defconfig where EFI_CAPSULE_FIRMWARE_FIT is enabled for test purpose.
