From 060fc704efbe92369e4c3b46954d75d0f36905f5 Mon Sep 17 00:00:00 2001 From: Chirag Shilwant Date: Mon, 12 Feb 2024 15:15:52 +0530 Subject: conf: machine: Apply U-boot fragment configs for AM62P Display Cluster Image - For AM62P tisdk-display-cluster image[1], Splash Screen is handled by SBL[2]. Hence, disable the A53 based U-boot Splash Screen using the am62px_evm_prune_splashscreen.config fragment present in ti-u-boot tree. - Apply a check on DISPLAY_CLUSTER_ENABLE variable[3] to ensure we apply am62px_evm_prune_splashscreen.config only incase of tisdk-display-cluster image as tisdk-default-image will still have the A53 based U-boot Splash Screen.
