i'm not sure about this. if you want to do size checking, then enable the hush shell and do it in a script.
Is there a programatic way to get the size of the flash at runtime from the hush script?
no. question is, do you really need that ? sounds like you know ahead of time how big the space is for u-boot, so the size of the flash doesn't matter.
Can't the same command also be used for burning something *other than* u-boot (e.g. a kernel, config section, or something like that)? So the size of the flash *does matter*, doesn't it?
How about using mtdparts which I think will tell you when you're going to write something larger than the defined partition? If it doesn't, that would be a handy thing to add (and be a general feature too).
