*
|

|
|
* 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:
|
||
|
|
* "BL1 by Nexell V1.0.0-gd551e13 [Built on 2018-01-25 16:58:29]"
