For consistency I would prefer to have all commands return the same type of information, i. e. either an error status (like we do with all other commands - any result values would then have to be passed as environment settings)
going through the env seems a little wonky. i dont know of any other commands that do this, so i dont think there's any standard to work off of here ...
I believe Wolfgang means for example this:
,----[ common/cmd_setexpr.c ] | U_BOOT_CMD( | setexpr, 5, 0, do_setexpr, | "set environment variable as the result of eval expression", | "[.b, .w, .l] name value1 <op> value2\n" | " - set environment variable 'name' to the result of the evaluated\n" | " express specified by <op>. <op> can be &, |, ^, +, -, *, /, %\n" | " size argument is only meaningful if value1 and/or value2 are memory addresses" | ); `----
ah, this makes things much more clear, thanks -mike
