Hi,

The header (NSIH) used for the s5p4418-SoC is not loaded into RAM by the 2nd-bootloader, see boot0.h. Therefore, use an adapted version of relocate_vectors which relocates the vectors after the header (at _start) instead of the 'dummy'-vectors at the start of the header (at __image_copy_start).
