There was a problem hiding this comment.
Is it possible to have more links to the corresponding ARM specification for each header?

Add Arm CCA as a supported AArch64 isolation platform and define the corresponding IGVM policy and VP context wire formats. Introduce IGVM_VHT_CCA_POLICY, IGVM_VHS_CCA_POLICY, CCA policy attribute bits, hash algorithm and LFA policy enums, and the AArch64 CCA VP context structure. Add parser, serializer, merge-mask fixup, and validation support for CCA policy headers, including reserved-field checks, ones/zeroes mask conflict detection, and validation that CCA policy compatibility masks refer to CCA platform headers. Add AArch64 CCA VP context directive handling and round-trip tests for CCA IGVM files. Expose the new CCA definitions through cbindgen and add the C API error mapping for invalid CCA policy compatibility masks.
