NAND parameters from SPI EEPROM
(1) The values listed only apply when operating in compatibility mode. These values follow the form 0xA1BCEDxx when operating in
standard mode.
Example: UBL_MAGIC_SAFE VALUE = 0xA1ACED00; Safe boot mode will configure the device to run in safe boot mode and in
compatibility mode. However, when using standard mode, the value should be 0xA1BCD00.
