CSF Header: RSA Signature

I'm trying to understand what is hashed/signed by the uni_sign tool. I'm only signing one binary (u-boot-spl.bin) so it takes as input an input file and the .bin file, and outputs a hdr.bin file.

In this header, there is a RSA signature, but I'm not sure of what ?


My goal is to perform secure boot while loading CSF / u-boot from the SD card. Right now the PBL loads everything, but the ISBC fails with error 0x341 (signature missmatch), so u-boot and linux runs in Non secure SEC state.
