config_distro_bootcmd.h was introduced in 2014. If we or these
distributions cannot update their packaging in a decade we cannot
support them. Simply hiding their inability to update their builds and
shifting the work to U-Boot is not acceptable.
As you have just demonstrated these legacy boot scripts have no way of
being tested. You've linked to a fundamental boot issue since the very
introduction of the beagleplay support. Obviously no one is using them.
a200f428b5b2 ("oard: ti: am62x: Add am62x_beagleplay_* ...
Fixing these scripts continue to signal to these distributions that
relying on custom scripting to boot their distribution rather than
packing a EFI stub or extlinux.conf file is acceptable.
The reason I'm trying to block this is because we will never be able to
remove them if we keep fixing them. I'm fine if we want to fix our
reference boards booting Arago, but we shouldn't block BeaglePlay from
cleaning up their codebase because of our reference distributions.
