On BeagleBone Black System Reference Manual SRM document,
Section 8.2 EEPROM, each cape has its own EEPROM containing data that will allow software to identify the board.
Section 5.3.2 32 KB EEPROM. A single 32KB EEPROM is provided on I2C0 that holds the board information. This information includes board name, serial number, and revision information.
Please help me to clarify myself that the bootloader uses the internal 32K EEPROM for board name, rev, etc.
