Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] The `hsm0: secure-enclave` node lacks the required `memory-region` property, and the `imx8ulp-firmware.dtsi` file mentioned in the commit message is missing.

arm64: dts: imx8ulp: add secure enclave node

This commit adds the EdgeLock Enclave (ELE) secure-enclave node to the
i.MX8ULP SoC dtsi. It also adds a label for sram@2201f000 that the node
references, while keeping the node disabled by default to avoid imposing
memory requirements.

[Severity: Medium]
Will this trigger a schema validation warning during make dtbs_check?

The fsl,imx-se.yaml binding strictly requires the memory-region property
for fsl,imx8ulp-se-ele-hsm. Since disabled nodes are validated by default,
leaving memory-region out of this base node causes validation to fail.

Additionally, the commit message mentions boards provide this property by
including imx8ulp-firmware.dtsi, but is that file missing from this patch
series?
