Commit Message

Atharv Dubey Sept. 4, 2026, 9:46 a.m. UTC 
Override name_initramfs in the deployed uEnv.txt so U-Boot loads
dm-verity-image-initramfs's cpio instead of ti-core-initramfs.
uEnv.txt is imported before bootcmd_ti_mmc runs get_initramfs_mmc,
so this override takes effect with no change to U-Boot itself.
