  1. Mask ROM runs integrity check on storage devices (NAND/SD/eMMC/USB).
  2. SPL (boot0/bootloader) from storage initializes DRAM.
  3. SPL loads U-Boot (or proprietary second-stage) into DRAM.
  4. U-Boot loads kernel + DTB + ramdisk from boot partition.
  5. Kernel mounts system partitions and starts Android init or Linux init.
