Currently OpenWrt uses its own detection and gpio/led/button configure code [0], but this doe not look nice to me. I saw Jonas RFC patch for device tree integration into bcm63xx [1] and thought about doing something similar for bcm47xx. Initially device tree would be used for mapping gpios to leds and buttons. I haven't read much about DT, but it looks nice. Is it possible to detect devices by some arbitrary nvram settings like it is done in diag.c?
