Does Raspberry Pi have a bootloader?
A bootloader is a program that loads the operating system. On the Raspberry Pi, the bootloader is stored on an EEPROM (basically just memory that persists even when the the device is powered off). Sometimes, for various reasons, that EEPROM can become corrupt, and needs to be reprogrammed.

The GPU starts executing the first stage bootloader, which is stored in ROM on the SoC. The first stage bootloader reads the SD card, and loads the second stage bootloader (bootcode.bin) into the L2 cache, and runs it.
