A recovery U-boot would only need to be generic enough to provide a console
and means to upload and run code through that console. If that works well,
then you have a reliable and (as) generic (as it gets) recovery u-boot
(granted, it would still depend on the console working out-of-the-boot
without any HW tricks like enabling voltage converters and such).
