Series [meta-ti,master,v4,1/3] dm-verity-upstream: Add dynamic layer for meta-security dm-verity | expand

Commit Message

Atharv Dubey Sept. 30, 2026, 12:59 p.m. UTC 
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.
