I don't like that method because it can easily be forgotten by someone changing bootargs for some other reason. IMO bootargs should only be used for configuration choices. I'd rather go for an additional parameter given by u-boot to linux with the address of the used u-boot environment, passed the same way that the address of bd_info is given to linux (for coldfire's, that's on the stack) Philippe _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
