The "Bootrom" (Boot Read-Only Memory) is the very first piece of code that runs when a chip powers on. It is burned into the silicon of the CPU/System on Chip (SoC) during manufacturing and cannot be changed. Its primary job is to initialize the CPU and look for a bootloader (like U-Boot) in external storage (NAND flash or eMMC).
