From b3ee5830c8a38524dcbda87f79ca971a8914734e Mon Sep 17 00:00:00 2001 From: Pankaj Gupta Date: Tue, 15 Sep 2026 01:10:03 +0530 Subject: arm64: dts: imx8ulp: add secure enclave node Add the EdgeLock Enclave (ELE) secure-enclave node to the i.MX8ULP SoC dtsi, together with a label for sram@2201f000 that the node references. Keep the node disabled in the SoC dtsi so it does not impose a reserved-memory requirement on every board. Boards enable the enclave and provide its memory-region by including imx8ulp-firmware.dtsi.
