While I appreciate the energy to get upstream, I think this habit of jumping ahead of kernel should be stopped. https://lore.kernel.org/all/20250522073426.329344-1-b-padhi@ti.com/ was posted, but not reviewed or accepted. I understand that there is a latency in picking things up in upstream kernel, but creating churn is not the right way of doing things. It took us an year+ to get OF_UPSTREAM settled down. At least wait for kernel maintainers to queue things up before attempting to sync u-boot with non-mainlined patches. -- Regards, Nishanth Menon Key (0xDDB5849D1736249D) / Fingerprint: F8A2 8693 54EB 8232 17A3 1A34 DDB5 849D 1736 249D
