I guess one thing I might mention here: I can imagine other partition-oriented commands existing, e.g. a command to find the bootable partition on a particular storage device. I'm not sure if we should create a single "part" command with various sub-options for this, e.g.: part uuid mmc 0:1 part get-bootable mmc 0 or create separate commands: partuuid mmc 0:1 part-get-bootable mmc 0 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
