During secure boot, Linux image along with other images are validated using bootscript. This bootscript also needs to be validated before it is executed. This requires a header for bootscript.
When secure boot is enabled, default bootcmd is changed to first validate bootscript using the header and then execute the script.
For ls2080, NOR memory map is different from earlier arm SoCs. So a new address on NOR is used for this bootscript header (0x583920000). The Bootscript address is mentioned in this header along with addresses of other images.
