15 | /* These structures define the layouts for the signed firmware image binary |
| 16 | * saved in NVRAM. The original image is in the Cryptographic message | |
| 17 | * syntax (CMS) format which contains the bootable firmware binary plus the | |
| 18 | * signatures. The entire image is written into NVRAM to enable the firmware | |
| 19 | * to validate the signatures. However, the bootrom still requires the | |
| 20 | * bootable-image to start at offset 0 of the NVRAM partition. Hence the image | |
| 21 | * is parsed upfront by host utilities (sfupdate) and written into nvram as | |
| 22 | * 'signed_image_chunks' described by a header. | |
| 23 | * | |
| 24 | * This file is used by the MC as well as host-utilities (sfupdate). | |
