Expose the FIREHOSE_OP_GET_SHA256_DIGEST primitive as a user-facing verb. The syntax mirrors the existing read / write / erase verbs and reuses parse_storage_address(), so addresses can be expressed as <P>/<S>+<L>, by GPT partition name, or any of the other supported forms. Each invocation prints one lowercase 64-character hex digest per region to stdout, so the output can be diffed against a sha256sum(1) line or piped into other tooling without further parsing. Typical use is verifying that what is on the device matches a known local image - useful on shared bench machines where multiple people flash the same board: $ qdl prog_firehose_ddr.elf sha256 xbl_a ... c288e50a94687a130a64db608c83678777ce5e7f9229248696c6f0dc41406cc9 $ qdl prog_firehose_ddr.elf read xbl_a xbl_a.bin ... $ sha256sum xbl_a.bin c288e50a94687a130a64db608c83678777ce5e7f9229248696c6f0dc41406cc9 Multiple sha256 verbs can be chained in a single invocation, with one digest line emitted per region in order.
