From: Simon Glass Date: Wed, 27 Dec 2023 21:06:59 +0000 (-0800) Subject: bloblist: Update the tag numbering X-Git-Url: http://git.dujemihanovic.xyz/html/static/gitweb.css?a=commitdiff_plain;h=e748e4b780057872b4a7192db87476adaa8b501c;p=u-boot.git bloblist: Update the tag numbering Align bloblist tags with the FW handoff spec v0.9. The most common ones are from 0. TF related ones are from 0x100. All non-standard ones from 0xfff000. Added new defined tags: BLOBLISTT_OPTEE_PAGABLE_PART for TF. BLOBLISTT_TPM_EVLOG and BLOBLISTT_TPM_CRB_BASE for TPM.
