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 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
