The situation is if we are fixing up or adding properties or nodes via the ft_board_setup() how do I go about modifying that before the device tree is handed to the kernel. An example would be if we start adding the i2c node via code in u-boot and after we have done that we want to add a frequency property at runtime w/o changing the u-boot code. - k ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ U-Boot-Users mailing list U-Boot-Users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/u-boot-users
