Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The `hsm0` node added to `imx8ulp.dtsi` lacks the `memory-region` property, which will cause `dtbs_check` schema validation to fail for any board that leaves the node disabled.

arm64: dts: imx8ulp: add secure enclave node

This commit adds the EdgeLock Enclave (ELE) secure-enclave node to the
i.MX8ULP SoC dtsi. The node is kept disabled by default so it doesn't impose
a reserved-memory requirement on every board.

[Severity: Low]
Will this missing memory-region property cause dtbs_check schema validation
to fail for boards that leave the node disabled?

The DT schema fsl,imx-se.yaml requires the memory-region property for the
fsl,imx8ulp-se-ele-hsm compatible unconditionally. Because dt-validate
evaluates all nodes in the resulting DTB, including those with
status = "disabled", any board including imx8ulp.dtsi that does not enable
the enclave and provide a memory-region will trigger a validation warning.
