When flashing a broken kernel, or an image where failsafe mode is no more accessible, recoverying these devices can become needlessly painful. Allow for easier recovery by unconditionally trying to get an initramfs image over TFTP once before booting, thereby giving the user a chance to sysupgrade to a working image.
Signed-off-by: Enrico Mioso <[email protected]> CC: Christian Lamparter <[email protected]> CC: David Bauer <[email protected]> --- Reasons for this patch: 1 - There are situations where it can be nice to recover a device without the AVM Recovery tool. In some cases the tool won't even be an option (as far as I know, it exists only for Windows, or am I wrong?). 2 - Since the effort of creating a second-stage bootloader for these devices has been carried out (thanks a lot for this!), I think it makes sense to allow for things to be more friendly to developers and users. Side effects: When nandboot fails, there will be TWO tftp requests with no delay between them, then the sleep will kick in. Possible "improvements": Implementing a push-button method may be preferred. Still, I have no easy way to attach an UART to the device right now. Moreover, being able to do this "more" remotely would be a vaulable feature to me.
