1. esbc_validate command is meant for validating header and signature of images (Boot Script and ESBC uboot client). SHA-256 and RSA operations are performed using SEC block in HW. This command works on both PBL based and Non PBL based Freescale platforms. Command usage: esbc_validate img_hdr_addr [pub_key_hash] 2. ESBC uboot client can be linux. Additionally, rootfs and device tree blob can also be signed. 3. In the event of header or signature failure in validation, ITS and ITF bits determine further course of action. 4. In case of soft failure, appropriate error is dumped on console. 5. In case of hard failure, SoC is issued RESET REQUEST after dumping error on the console. 6. KEY REVOCATION Feature: QorIQ platforms like B4/T4 have support of srk key table and key revocation in ISBC code in Silicon. The srk key table allows the user to have a key table with multiple keys and revoke any key in case of particular key gets compromised. In case the ISBC code uses the key revocation and srk key table to verify the u-boot code, the subsequent chain of trust should also use the same. 6. ISBC KEY EXTENSION Feature: This feature allows large number of keys to be used for esbc validation of images. A set of public keys is being signed and validated by ISBC which can be further used for esbc validation of images.
