From 045eeb7b76e40ea881166ddd3f780109d9092c5f Mon Sep 17 00:00:00 2001 From: Atharv Dubey Date: Mon, 5 Oct 2026 17:42:17 +0530 Subject: [PATCH] linux-ti-staging: Add dm-verity kernel config Add a kernel config fragment enabling dm-verity and its crypto dependencies (CONFIG_DM_VERITY, CONFIG_DM_CRYPT, CONFIG_BLK_DEV_DM). Applied via KERNEL_CONFIG_FRAGMENTS, which setup-defconfig.inc reads and merges directly through merge_config.sh. Gated on DM_VERITY_IMAGE being set, matching the rest of the dm-verity dynamic layer.
