My thought here is that I would like the command line to influence U-Boot right from the start, before board init. If we don't know our parameters until then, then we might do something we shouldn't. For one thing, if the arguments are --help then we are wasting our time. One little niggle is that it isn't really possible at present to call printf() too early. I have left it along for now, and just come back later and print usage, but it *might* be necessary at some point to implement os_printf() or similar to allow messages from Sandbox. > > in terms of processing the state, i think we can just make this into an init > func that runs before we let board_init_r tail into main_loop Well the requirement may be that we don't even want to run main_loop - see the next patch. > -mike Regards, Simon _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
