| * The NSIH (first 512 Bytes of u-boot.bin) is necessary for the |
| * 2nd-Bootloader to get information like load address of U-Boot. |
| * |
| * 0x400 must be added to CONFIG_SYS_TEXT_BASE to have the actual load and |
| * start address because 2nd-Bootloader loads with an offset of 0x400 |
| * (NSIH + 0x200 bytes are not loaded into RAM). |
| * |
| * It has been tested / is working with the following 2nd-Bootloader: |
