Major architecture change: move from BSP kernel 6.6 with pre-merged panel
DTBs to mainline kernel 6.12.61 LTS with separated board DTBs + panel
overlays.
- Board DTB = hardware profile (GPIOs, PMIC, joypad, audio). 16 boards.
Auto-selected by U-Boot via SARADC ADC reading (hwrev).
- Panel overlay = display init sequence. 20 panels. Applied at boot time
via boot.ini fdt apply.
- Two image variants: original (a_boot.ini) and clone (b_boot.ini)
- Kernel cross-compiles from x86 host (no ARM chroot needed)
- Initramfs boot splash with SVG rendering at 0.7s
- Out-of-tree joypad driver (singleadc-joypad) for clone boards
- Panel generic-dsi driver with archr,generic-dsi compatible
