Dear Maintainer,


   * I'm searching a solution to implement a fallback kernel mechanism
     in case of boot failure. 'u-boot' has this ability, but it must be
     enabled. See some example at
https://github.com/balena-os/balena-raspberrypi/blob/master/layers/meta-balena-raspberrypi/recipes-bsp/u-boot/u-boot/configs-Add-bootcount-configs-to-rpi-defconfigs.patch
   * From the debian sources, it appears this option is not selected. It
     would be great to at least test if enabling it permits to
     effectively work around boot failures.

It would be ideal to get this addressed in upstream u-boot:

https://www.denx.de/wiki/U-Boot

... unless there is some particular reason this would only make sense in
the context of Debian? Not sure what that would be.


live well,
