This shaves 400ms of a FIT image boot that uses sha256 as digest for the images referenced by the selected configuration: barebox@imx8mn-old:/ time bootm -d kernel-a Dryrun. Aborted. time: 998ms barebox@imx8mn-new:/ time bootm -d kernel-a Dryrun. Aborted. time: 601ms We also use SHA256 to verify barebox proper when in high assurance boot, but that still uses the software implementation.
