+extlinux.conf is a file which has a final word when describing how to boot your device.
+
+Usually u-boot runs boot.scr which checks some hardware stuff (ADC voltage, some GPIO levels),
+chooses a dtb based on collected data and passes that to extlinux.
+
+Thay may fail if you have a rare device or faulty hardware or something else unexpected.
+In this case you can configure extlinux.conf manually.
+Main things to edit:
+ * APPEND -- kernel cmdline. If you have UART soldered you may want to remove 'quiet' option.
+   Also this parameter can modify kernel behaviour (e.g. disable or configure drivers)
+ * FDT -- a path to .dtb file to use. Please note that uboot's extlinux has a poor parser,
+   and even a space after dtb file path breaks the boot.
+ * FDTOVERLAYS -- dtb overlays to apply. This line can point to non-existing files, that's ok.
+   Overlays may be used to apply configuration specific to your device
+   (e.g. joystic axis inversion, display init sequence, etc.)

+Here your device tree overlays live.
+Currently only mipi-panel.dtbo is expected which is intended for display driver stuff.
+
+For R36s, rg351*-v2 and maybe other devices you may need to put a proper mipi-panel.dtbo
+to make display work.
+See https://rocknix.org/devices/unbranded/game-console-r35s-r36s/#new-displays-r36s-of-year-2024
+
+Despite the name, mipi-panel.dtbo is also abused for quite a complex tuning
+of EE clones of year 2025, but in this case the overlay is usually generated automatically.
+In some cases (something is misdetected) you may want to replace mipi-panel.dtbo
+with whatever you need.
