Hi Colin,
> This change introduces a development-phase devicetree for the
> Facebook Anacapa BMC EVT1 hardware revision and updates the Anacapa
> wrapper DTS to reference it.
>
> A dedicated EVT1 DTS is added for revision-specific hardware while
> keeping a single, Anacapa entrypoint used by the build and deployment
> flow. The top-level aspeed-bmc-facebook-anacapa.dts
