That seems like the best solution, but we don't have control over the
bootloader in most cases. We have an alternative implementation (ie
mainline u-boot) that is required for a few things already, but I'd
really like to still be able to at least boot the kernel on a "legacy"
bootloader (that is the one flashed on the device).
