28 * Initial Bootloader is in embedded flash.
29 * Vital Product Data, U-Boot Environment are in I2C-EEPROM.
30 * U-Boot is in embedded flash, a backup U-Boot can be in NAND flash.
31 * kernel and file system are either in NAND flash or on a micro SD card.
32 * NAND flash is optional.
33 * I2C EEPROM is never optional.
34 * SPI FRAM is optional.
35 * SPI ENC28J60 is optional.
36 * 16 or 32 bit wide SDRAM.
42 * Warning: changing CONFIG_SYS_TEXT_BASE requires
43 * adapting the initial boot program.
