Most Allwinner sunxi SoCs have separate boot ROMs in non-secure and secure mode. The "non-secure" or "normal" boot ROM (NBROM) uses the existing sunxi_egon image type. The secure boot ROM (SBROM) uses a completely different image type, known as TOC0. A TOC0 image is composed of a header and two or more items. One item is the firmware binary. The others form a chain linking the firmware signature to the root-of-trust public key (ROTPK), which has its hash burned in the SoC's eFuses. Signatures are made using RSA-2048 + SHA256. The pseudo-ASN.1 structure is manually assembled; this is done to work around bugs/quirks in the boot ROM, which vary between SoCs. This TOC0 implementation has been verified to work with the A50, A64, H5, H6, and H616 SBROMs, and it may work with other SoCs.
