Allwinner A23 Firmware < Direct 2027 >

Use mainline U-Boot and Linux when feasible; contribute board patches upstream.
Replace FEX with DTB and get board support merged to reduce future maintenance.
Package userspace to minimize attack surface; enable hardened kernel options (ASLR, SELinux/AppArmor if possible).
Where encryption or verified boot is needed, evaluate hardware capabilities (e.g., secure boot fused ROM) and implement a signing workflow.
